± groups and -ray transitions have been observed from nuclides produced in the bombardment of Ca40 with I127. Two weak ± groups were assigned to Ta162,163 based on their measured half-lives and excitation functions. With an unambiguous assignment of these two ± groups the absolute masses of nuclides in two long ± chains, for which Ta162,163 form links, can now be deduced with confidence. Absolute masses are thus obtained for some nuclides very far from stability, including ones that are not bound against ground-state proton emission. The simultaneous observation of ± groups and rays from other nuclides produced in this bombardment also permitted the determination of the upper limits of six new ± branching ratios. © 1992 The American Physical Society.
