Finite-element multiconfiguration Hartree-Fock calculations of the atomic quadrupole moments of excited states of Be, Al, In, Ne, Ar, Kr, and Xe.

Abstract

The atomic quadrupole moments Q zz of Be(2s2p; 3 P 2 ), Al(3p; 2 P 3/2 ), In(5p; 2 P 3/2 ), Ne(2p 5 3s 3 P 2 ), Ar(3p 5 4s; 3 P 2 ), Kr(4p 5 5s; 3 P 2 ), and Xe(5p 5 6s; 3 P 2 ) have been calculated using a finite-element multiconfiguration Hartree-Fock method. The obtained Q zz (Be) of 2.265 a.u. agrees with previously calculated values
