ExperimentalQ β-values of several short-lived nuclides with mass number 85≦A≦103

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

TheQ β-values of85, 86Se,90Br,93Kr,103Nb and103Tc were measured using massseparated sources produced at the on-line mass separator LOHENGRIN. The experimental values are compared with mass formula predictions. Taking also into account earlier results, a subshell-closure effect for the neutron numberN=56 and proton numberZ=38 is shown to exist.
