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

The energies of the Kα₁, Kα₂, Kβ₁, and Kβ₃ 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 LII-, LIII-, MII-, and MIII-shell binding energies. The relative transition probabilities (Kα₁=1000) 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.
