Dipole-dipole polarizability of the cadmium $\mathbf{^1S_0}$ state revisited

Abstract

Germany a)Experimental results and high-level quantum chemical ab initio calculations of the static polarizability α 0 = α(ω = 0) of the cadmium 1 S 0 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 α 0 will shift from 49.7 ±1.6 au to considerably lower values. We now conclude an experimentally determined polarizability of α 0 = 47.5 ± 2.0 au in much better agreement with the latest calculations of α 0 ≈ 46 au.

Relativistic normal coupled-cluster theory analysis of second- and third-order electric polarizabilities of Zn I

“…The RNCC method has been applied previously for the accurate determination of α d values for Xe, Cd and Hg atoms [34][35][36], resulting in a reconciliation between the theoretical and experimental polarizability values for the Cd atom [35]. This immediately prompted a re-analysis of the experimental data for this atom [37]. A recent calculation of α d of Cd using the finite-field approach in the RCC theory framework offers further support to these findings [38].…”
