A theoretical study of spectral profiles near the Kr and Xe resonance lines of the 1,3P1–1S0
transitions produced in the atmosphere of helium under equilibrium conditions is performed.
Potential energy curves for the excited states of the Kr(4p55s)+He and Xe(5p56s)+He
quasimolecules are obtained in the framework of the consistent use of the effective Hamiltonian
method and the pseudopotential method. For the ground state experimental data are used. Based
on quasistatic approach the spectral profiles of the quasimolecular absorption and radiation in the
short-wave region of the resonance lines are calculated by applying the potential energy curves
obtained. The resulting profiles are compared with experimental ones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
