Fine-structure-changing collision cross sections within the low-lyingnD2states of rubidium induced by ground-state rubidium atoms

Lifetime and Collisional Depopulation Cross Section for the 142D3/2State of Rb

“…The lifetime for Rb (14 2D), the state of interest to the present work, had been also earlier calculated, within Coulomb approximation method, by Gounand [9]. Experimentally determined cross sections for depopulation of Rb(n 2D3) states induced by collisions with ground-state Rb atoms are available for n ranging from 5 to 15, with an exception of n = 14 [7,[10][11][12][13][14][15][16][17]. In experiments involving different procedures, cross sections for different collisional depopulation processes were obtained: the ones for mixing between the doublet components (cross section am ;.)…”

Excitation energy transfer in the Li-Cs collision: Li*(2P)+Cs(6S)→Li(2S)+Cs*(5D)

“…Among the most investigated processes are the collisions involving atoms excited in the resonance state (first P level). In more recent papers excitation transfers between the highly excited states have been studied in order to determine the dependence on energy and quantum numbers of the levels involved [4,5,6,7]. Most results in this field were published until 1975 and summarized in [1,2].…”
