Abstract

A previously published measurement of the reaction of a 59 MeV/nucleon ${}^{14}{Be}$ beam on a deuterated polyethylene target was further analyzed to search for ${}^{12}{He}$ as well as initial state effects in the population of the ${}^{10}{He}$ ground state. No evidence for either was found. A lower limit of about 1 MeV was determined for a possible resonance in ${}^{12}{He}$ . In addition, the three-body decay energy spectrum of ${}^{10}{He}$ could not be described by a reaction mechanism calculation based on the halo structure of the initial ${}^{14}{Be}$ assuming a direct $α$ -particle removal reaction.
