K-Series X-Ray Energies and Intensities for Curium, Berkelium, Californium, and Einsteinium

Abstract

The energies of the $K{\alpha }_1$, $K{\alpha }_2$, $K{\beta }_1$, and $K{\beta }_3$ x rays of Cm, Bk, Cf, and Es, arising in the decay of suitable parent radioactivities, have been measured with a high-resolution Ge(Li) photon detector. The $K$-shell binding energies of Cm, Bk, and Cf have been determined using previously published values for the $L_{\mathrm{II}}$-, $L_{\mathrm{III}}$-, $M_{\mathrm{II}}$-, and $M_{\mathrm{III}}$-shell binding energies. The relative transition probabilities ($K{\alpha }_1=1000\mathrm{}$) of the $K$-series lines have been determined for Cm, Bk, Cf, and Es. The measured energies and relative transition probatilities agree well with recent theoretical predictions.
