Abstract

The angular distribution coefficients $b_{k} E λ(ξ) and b_{k} M λ(ξ)$ of the gamma-rays emitted by nuclei excited by Coulomb excitation are calculated in the limit ξ⪢1 with the use of asymptotic expansions of the Coulomb integrals. These coefficients are expressed as series expansions with $ξ^{−23}$ as expansion parameter; the expansion coefficients are evaluated numerically. Numerical values of $a_{k} πλ(ξ) (b_{k} πλ(ξ)/b_{0} πλ(ξ))$ are presented for 5<ξ<140.

We present techniques for evaluating the coefficients of the leading terms for both the high (ξ = 0) and low (ξ å 1) energy limits of classical nuclear Coulomb excitation. Results are given for ion-induced electric and magnetic transitions up to λ = 10 that are required for astrophysical calculations of the effectiveness of certain stellar environments in enhancing the radiative deexcitation rates of important long-lived isomeric states.
