Abstract:
TheQ β-values of the very neutron-rich cesium isotopes with mass number 142≤A≤146 have been measured with a plastic scintillation detector telescope at the fission product separator OSTIS. The mass excesses calculated from these decay energies agree well with the values obtained by direct mass determinations.
