first_imgBEIJING — Luis Scola was asked what Sunday will mean to him, and he didn’t hesitate with the answer.“Everything,” he said.The veteran Argentinian forward didn’t need to give more of an explanation. The World Cup is one win away, and Scola made sure his team would have a chance to hoist the trophy.Scola scored 28 points and grabbed 13 rebounds, sealing the deal with 3-pointers on consecutive possessions down the stretch, and Argentina beat France 80-66 on Friday in a World Cup semifinal. Argentina will play Spain in the gold-medal game on Sunday.Gabriel Deck scored 13 points and Facundo Campazzo added 12 for Argentina, a team with no active NBA players on its roster and still made its first gold-medal game in Olympic or World Cup play since the 2004 Athens Games. And when he made his way to the locker room, Scola was greeted by chants of “M-V-P” from teammates.He corrected them with a smile: “MBP,” he said. “Most Beautiful Player.”Indeed, on the court the 39-year-old’s game is still very much a thing of beauty. Showing no signs of fatigue, he played 34 of the 40 minutes and saved his best for the very end.“Luis told us before every game, including today, that we can win — that we are a tough, tough team to beat,” Argentina center Tayavek Gallizzi said. “Just focus on our game. It’s incredible. At his age he is playing better than all the younger guys.”Frank Ntilikina and Evan Fournier each scored 16 for France, which will play Australia for the bronze on Sunday. Nando De Colo scored 11 for France, a team that looked nothing like the one that topped the U.S. in the quarterfinals on Wednesday.Rudy Gobert, who led France in that win over the Americans, scored only three points against Argentina.“From the first to the last minute, it was complete domination,” Gobert said, tipping his cap to Argentina.Rudy Gobert of France dunks the ball during their semifinal match against Argentina in the FIBA Basketball World Cup at the Cadillac Arena in Beijing, Friday, Sept. 13, 2019. (AP Photo/Mark Schiefelbein)Both semifinal winners got two days off after their quarterfinal victories. Australia and France both played their quarterfinals on Wednesday, and France coach Vincent Collet said he thought that was a factor.“I didn’t want to find any excuse, but I think so,” said Collet, who cancelled practice Thursday because of his team’s travel demands. “For me, it’s not fair that one team has two days to recover and prepare even if they don’t know the first day who will be the opponent. They know it’ll be one or the other, so they can prepare for both.”Argentina put together an early 10-0 run to take the lead, and kept it the rest of the way. A 15-point lead got cut to single digits for much of the fourth, when Scola’s back-to-back 3s clinched the outcome.“It was a great game for us,” Campazzo said.TIP-INSFrance: The French still have a chance to match their best World Cup finish, third in 2014 … Vincent Poirier took a hard fall under the Argentina basket while fighting for a rebound late in the third quarter. He was able to get to the bench a few moments later. … France fell to 1-5 against Argentina in major tournaments.Argentina: Manu Ginobili, the longtime San Antonio standout and the leading Argentina-born scorer in NBA history, was courtside watching his national team. Fellow retired NBA stars Kobe Bryant and Chris Bosh were also courtside. … It took Scola only 16:45 of playing time to get a double-double; he grabbed his 10th rebound with 21 seconds left in the half and already had 13 points.REVENGEArgentina scored a bit of World Cup comeuppance. France and Argentina most recently met in a World Cup just last year — the soccer version. France ousted Argentina in the round of 16, prevailing 4-3 on its way to winning the title.LOOKING AHEADSpain has faced Argentina nine previous times in top-level international competition and has a decided advantage in the rivalry. Spain is 7-2 against Argentina in those meetings, the most recent one being a 19-point win at the Rio Olympics three years ago.UP NEXTFrance: Faces Australia for bronze medal in Beijing on Sunday.Argentina: Faces Spain for World Cup championship in Beijing on Sunday.By: Tim Reynolds, AP Basketball WriterTweetPinShare0 Shareslast_img read more


first_img High-Flying Electrons May Provide New Test of Quantum Theory (PhysOrg.com) — When Enrico Fermi investigated the Rydberg atom in the ’30s, he never imagined that the giant atoms could form molecules. Later, in the ’70s and ’80s, theoretical physicist Chris Greene predicted that Rydberg molecules could exist. But it wasn’t until recent advancements in ultracold physics that such an observation has been made possible. A recent study now shows that the Rydberg molecule can be created in the lab, and its observation supports decades of theory. Explore further In a paper published in Nature, scientists from the University of Stuttgart in Germany and the University of Oklahoma in the US explain how they have created Rydberg molecules with a calculated lifetime of 18 microseconds. Their Rydberg molecule consists of two rubidium atoms, one a Rydberg atom and one a groundstate atom. Connected by a very weak chemical bond, the two atoms are separated by about 100 nm (several thousand Bohr radii), which makes them much farther apart than atoms in most other molecules.As opposed to groundstate atoms, Rydberg atoms are excited atoms that have one electron in an outermost orbit very far from the nucleus (a state with a very high principal quantum number). For this reason, Rydberg atoms are large and can exhibit unusually long-range interactions. For example, scientists have previously investigated the bonding of two Rydberg atoms, which occurs across very large internuclear distances.In the current study, the scientists investigated a different bonding interaction, which occurs between a Rydberg electron and a groundstate atom. As the researchers explain, this bond arises from the low-energy scattering of the Rydberg electron with the negative scattering length from a groundstate atom when the atoms are at a specific location within the Rydberg electron wavefunction. To observe these giant molecules, the researchers prepared a magnetically trapped sample of ultracold rubidium atoms. As the rubidium cloud cooled, the atoms in the gas moved closer together. At temperatures close to absolute zero (-273°C), the atoms’ nuclei were separated by the critical distance of 100 nanometers. The researchers then excited some of the atoms to the Rydberg state with a laser. “If we have a gas at the critical density, with two atoms at the correct distance that are able to form the molecule, and we excite one to the Rydberg state, then we can form a molecule,” said Vera Bendkowsky of the University of Stuttgart, lead author of the study. Using spectroscopic techniques, the researchers could investigate these exotic molecular states, such as determining the 18-microsecond lifetime of the molecules. The experimental results agree well with predictions, confirming long-held fundamental atomic theories. Based on the results of their spectroscopic characterization, the scientists predict that other states could be realized and investigated in the near future. One possibility is the realization of “trilobite molecules,” which are bound states involving a Rydberg electron with large angular momentum.More information: Vera Bendkowsky, Bjorn Butscher, Johannes Nipper, James P.
