Abstract

The beta-decay of Sn-105 was re-investigated at the ISOL facility of GSI Darmstadt by using a total absorption spectrometer. The experimental results include the half-life and beta-delayed proton branching ratio of 32.7(5)s and 1.1(4). supercript stop10(-4), respectively, and the contribution of electron capture to the Sn-105 decay of 0.420(35). The Gamow-Teller strength distribution peaking at 3.6MeV was measured, yielding a summed Gamow-Teller strength of 3.0(4). The latter data are discussed in comparison with shell-model predictions based on an empirical interaction.
