Abstract
A new neutron-rich isotope, , was produced by (25-200-MeV neutrons) and by (92-MeV protons). Chemically separated sources were used to study its and decay and the following characteristics were observed: min; MeV; keV. A decay scheme for is proposed based on the experimental data and on theoretical predictions for the excited level structure of . A - of 1.27 MeV was inferred from - coincidence measurements.
