RADIATIVE LIFETIMES OF THE EXCITED ELECTRONIC STATES OF CUCL

Spontaneous radiative lifetimes of the observed electronic states of CuCl have been calculated using a model including spin-orbit interaction mixings within the Cu+ (3d(9)4s) Cl- (3s(2)3p6) structure. The required wave functions have been determined semiempirically and locations of the as-yet unobserved components have been estimated. For the A3SIGMA1+, C3PI0e, D1PI1, E1SIGMA0+, and F3DELTA1 components, the lifetimes calculated in the simple single-configuration pure-precession approximation with a slight modification in the OMEGA = Oe block are in good agreement with earlier experimental measurements. On the contrary, for the B3PI1 component, there is a marked discrepancy that cannot be reduced except by assigning very unlikely values to the off-diagonal spin-orbit parameters.
