摘要: Temperature dependent emission spectra of spin excited iodine in crystalline Xe and Kr are presented analyzed terms nonadditive anisotropic pair interactions. In the octahedral trap site, atomic 2P states split into E1/2 G3/2 groups double valued representation. The fourfold degenerate state is subject to strong Jahn–Teller instability further splits by coupling phonons E3/2 Kramers pairs. Accordingly, observed composed two bands: 2E1/2→1E1/2 2E1/2→E3/2 transitions. Two pairs bands each Kr. long‐lived (at 15 K, τ=250 μs 930 Kr, respectively) assigned isolated atom, while a short lived τ<1 Xe, τ=2.2 Kr) I atoms trapped as nearest neighbor localized charge, identified (HRg)+. atom simulated Monte Carlo methods which assume classical statistics heavy coordinates...
