Nuclear Data Sheets for A = 103

Abstract

The 1961 version of the Nuclear Data Sheets for A = 103 has been revised on the basis of experimental data received prior to March 1, 1974. Information from approximately 150 papers and communications has been included in the present evaluation. Data on nine A = 103 nuclei are presented. The compilers regard the assignment of fission-fragment γ-rays to 103Zr and 103Nb as uncertain, and no measurements on the decay of these nuclei have been made. The half-lives of 103Mo and 103Cd are known, but no decay schemes have been proposed. The compilers propose a decay scheme for 103Tc based mainly on unpublished measurements, but further work is needed to determine absolute transition intensities and the decay energy. The decay schemes for 103Ru, 103Pd, and 103Ag appear to be well established on the basis of extensive but mainly unpublished results. The spins of a few low-lying levels in 103Ru are determined by single-nucleon transfer reactions. Spin assignments have been made for most low-lying levels in the stable nucleus 103Rh from 103Ru decay, 103Pd decay, and Coulomb excitation. The spins of many levels in 103Pd have been determined from extensive unpublished results in 103Ag decay, single-nucleon transfer reactions, and in-beam γ-ray studies. Only one excited level is known in 103Ag. For papers concerned with nuclear structure theory for A = 103 nuclei, see 66Sh18, 72Ku25, 73Bo16, and 73Im01.
