Hyperfine Induced Transitions as Diagnostics of Isotopic Composition and Densities of Low‐Density Plasmas

Abstract

The J \ 0 ] J@ \ 0 radiative transitions, usually viewed as allowed through two-photon decay, may also be induced by the hyperne (HPF) interaction in atoms or ions having a nonzero nuclear spin. We compute new and review existing decay rates for the transitions in ions of the Be nsnp 3P
