U. Hohm et al., ELECTRIC-DIPOLE POLARIZABILITY OF AS-4, A CHALLENGING PROBLEM FOR BOTH EXPERIMENT AND THEORY, The journal of physical chemistry. A, Molecules, spectroscopy, kinetics, environment, & general theory, 102(8), 1998, pp. 1237-1240
An experimental value of 116.7 +/- 1.1 e(2)a(0)(2)E(h)(-1) for the Sta
tic dipole polarizability of As-4 is deduced from the analysis of refr
activity measurements in arsenic vapor. This is in close agreement wit
h the theoretical result of 119.5 +/- 3.6 e(2)a(0)(2)E(h)(-1), obtaine
d from ab initio finite-field many-body perturbation theory and couple
d-cluster calculations.
