The shape of the nuclear mass surface far out on the neutron-rich side of β-stability is of considerable interest because of many interesting applications, e.g. theories about the r-process in nucleosynthesis. Until now, direct mass determinations have been performed in very few cases1). Most studies of the mass surface have been carried out by the method of determining mass differences from measurements of total β-decay energies. The latter method has been used at Studsvik for a systematic investigation covering about 40 fission products in the mass ranges A = 75 - 89 and A = 120 - 135 and including isotopes of zinc, gallium, germanium, arsenic, indium, tin, antimony, and tellurium2-6).
