Dynamic dipole polarizabilities forthe ground 4 1S and the low-lying 4 1,3P and5 1,3S excited states of Zn. Calculation oflong-range coefficients of Zn2

Abstract

Dynamic dipole polarizabilities for the ground 4 1Sand the low-lying 4 1,3P and 5 1,3S excitedstates of Zn are calculated by the time-dependentgauge-invariant method and compared with otherexperimental and theoretical results. The wavefunctionsare obtained from multi-referenceconfiguration-interaction calculations using atwo-electron relativistic pseudopotential. Core-valencepolarization is accounted for by the use of asemi-empirical core-valence potential.Core-polarization effects are also considered whencalculating the oscillator strengths using a modifieddipole transition operator. Long-range coefficients forthe molecular states of Zn2 dissociating into: 4 1S+ 4 1S; 4 1S + 4 3P; 4 1S + 4 1P; 4 1S +5 1S and 4 1S + 5 3S are presented.
