Dipole-dipole polarizability of the cadmium -=SUP=-1-=/SUP=-S-=SUB=-0-=/SUB=- state revisited -=SUP=-*-=/SUP=-

Abstract

Experimental results and high-level quantum chemical ab initio calculations of the static polarizability α=α(ω=0)) of the cadmium 1S0 state are still in marked disagreement. Here we analyze this discrepancy by using experimentally determined dipole oscillator strength distributions (DOSD). It will be shown that within this procedure the experimentally determined static polarizability α0 will shift from 49.7± 1.6 au to considerably lower values. We now conclude an experimentally determined polarizability of α0 = 47.5 ± 2.0 au in much better agreement with the latest calculations of α0~ 46 au. Keywords: cadmium, polarizability, DOSD
