Abstract

A search has been conducted for the exotic neutron rich nucleus ${}^{10}{He}$ among projectile fragments produced by an E/A=30 MeV ${}^{18}O$ beam. No ${}^{10}{He}^{2 +}$ ions were observed. The upper limit on the production rate of ${}^{10}{He}$ is determined to be less than 3× $10^{- 5}$ that of ${}^{8}{He}$ .
