Abstract
In bombardments of with we discovered the α-decaying nuclide . We conducted an extensive off-line search of the raw data for event sequences which fit the expected pattern of implantation in a position-sensitive detector and subsequent decay of and its descendants. We observed one three-member sequence of genetically linked α decays, resulting in =11.35 MeV, a half-life of 0. ms, and a production cross section of about 0.4 pb for . Other possible event chains were also observed. The measured α-particle energy for the N=163 nuclide provides direct evidence for a neutron shell closure at N=162. © 1996 The American Physical Society.
