Abstract
The decay of neutron-rich has been studied at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. By using a high-resolution mass separator a purified beam was obtained, thus allowing decay through its isobar chain to stable without any decay chain member dominating. A total of rays were associated with decay with 111 placed in the level scheme. Updated feeding intensities and estimated values are presented, and new assignments are proposed using shell model calculations. The progression of simulated total absorption -ray spectroscopy (TAGS) based on proposed levels and -feeding values from previous measurements to this evaluation are presented and demonstrate the need for a TAGS measurements for this and similar decays.
