Potential energy curves and dipole transition moments for excited electronic states of XeKr and ArNe

“…3, enlarged plots of the 0 Ϫ (I), 1͑I͒, 2͑I͒, 1͑II͒, and 0 ϩ ͑II͒ potentials in the region around the energy minima are given. The present results are in qualitative agreement with the previous model potential calculations [23][24][25] ͑cf. plots of potentials in Krylov et al 1 ͒ although the well depths and the position of the minima are not identical, as will be discussed below.…”

“…23,24 Similarily, in the present work, there is no evidence for a double well potential for 0 ϩ ͑II͒, with a single minimum of 585 cm Ϫ1 found for this state at 6.9 bohr. It is possible that the experimental deductions 19 might change if the potentials and transition moments of the present work are employed in the analysis of the spectra.…”

“…17 However, it is more likely that the reported data should be assigned to the 0 ϩ ( 3 P 1 ) exciplex. 25 Model potential calculations predict deeper minima for the exciplex states, ranging from 1000-1200 cm Ϫ1 ͓for the 0 Ϫ ( 3 P 2 ), 1( 3 P 2 ), and 0 ϩ ( 3 P 1 ) states͔ and around 300 cm Ϫ1 ͓for the 2( 3 P 2 ) and 1( 3 P 1 ) states͔, [23][24][25] while simulations of absorption spectra employing Morse potentials with parameters obtained from the above calculations found 170 cm Ϫ1 to be a more suitable value for the well-depth of the 1( 3 P 1 ) state. 22 Thus it is a rather confusing situation, considering that the emission spectra of XeKr overlap with those of the homonuclear dimer, Xe 2 and the fact that the excited states corresponding to a particular limit are closely lying and also lead to overlapping emission spectra.…”

Analysis of Broadening and Shift of the 326.1 nm Cd Line by He and Ne

“…In paper [18] the interaction potentials for the Cd(5 3ΡJ) + Rg (Rg = He, Ne) systems were calculated using the effective Hamiltonian method [28] on the basis of approach given by [32,33]. This formulation takes into account an intermediate type of coupling of the electron angular momenta of the excited atom.…”

Quasimolecular emission near the Xe(5p56s1,3P1– 5p6 1S0) and Kr (4p55s1,3P1– 4p6 1S0) resonance lines induced by collisions with He atoms

“…The potential curves of the interaction of excited atoms Kr(4p 5 5s) and Xe(5p 5 6s) with He atoms in the ground state were calculated in [1,2] in the framework of the method of the effective Hamiltonian in the formulation [3] and the pseudopotential method [3]. Previously, these potential curves have been already applied for the calculations of absorption spectra of Xe + He and Kr + He mixtures and the results obtained are in good agreement with the experimental data [4].…”
