Abstract
TheQ β-values of101Rb,101,102Sr and101,102Y have been measured for the first time at the mass separator ISOLDE by means ofβγ-coincidence techniques with a plastic scintillation detector telescope and a large Ge(HP)-detector. For some of these nuclei, also new details of their decay schemes could be derived from the measuredβ-decay properties. The experimental results are discussed, as far as the systematics of two-neutron separation energies derived from them is concerned. In addition, the nuclear masses deduced from theseQ β-values are compared with the predictions of recent mass calculations.
