Cross section for the photochemical formation of the NaZn (22Π) excimer
We studied the conditions for the photochemical formation of the NaZn excimer in the excited 22Π state using Na2(21Π u )+Zn→NaZn(22Π)+Na reaction. The Na-Zn vapor mixture was prepared in the heat-pipe oven with the well defined column density and temperature. The Na and Zn atom densities in the vapor mixture were controlled by the preparation of the alloy with different mole fraction ratios of the relevant components in the solid phase. The Na densities were determined from the total absorption coefficient at Na2 X-B and X-A bands. The cross section for photochemical formation of the NaZn in the 22Π state is estimated to be 17·10−16 cm2 for the laser excitation at 308 nm, measured relative to the cross section of 470·10−16 cm2 for collisional energy transfer Na2(21Π u )+Na→Na2(23Π g )+Na published by Mehdizadeh et al. [2].
