    Abstract:
    Populations of the n2 L (nL = 7P, 6D) states of Cs atoms by photodissociation of Cs2 molecules through the use of the fixed frequence line 441.6 nm of a He-Cd laser radiation are produced. Combining ratios of atomic to molecular fluorescence at the Cs density range between 1 and 9 x 10(15) cm(-3), the ratios of collisional rate coefficient to predissociation rates are estimated to be 2.9 x 10(-17) cm3 and 7.4 x 10(-18) cm3, respectively. The branching ratios are defined as the ratios of nL(J) to nL(J) fluorescence. The ratios of the dissociation rates produced in n2 L fine-structure states are 0.53 and 0.43, respectively. Fine-structure changing cross section has been measured for far wing excitation, the result is consistent with cross section obtained from other excitation of the n2 L states. The cross section for excitation transfer out of the 6D doublet [i.e., Cs(6D) + Cs(6S) --> states other than Cs(6D)] is 1.9 x 10(-14) cm2.
