Spectroscopic studies of the 1_u reversible X0_g~+ transition in Cd_2 and Zn_2: test of the potential barrier in the excited states 1_u(5~1P_1)Cd and 1_u(4~1P_1)Zn

摘要

The blue satellite of the Cd resonance line at 228.8 nm has been studied in both absorption and emission. Comparison of experimental data with quantum simulations of the spectrum basing on available theoretical potential energy curves yielded a correction for the theoretical height of the potential energy barrier in the state 1_u(5~1P_1) Cd. Similar correction seems to be necessary for the analogical state of Zn.
