Abstract

A strong population of the " $j$ -forbidden" $4^{+}$ level at 4.25 MeV in ${}^{20}{Ne}$ is found in the reaction ${}^{19}F$ ( ${}^{16}O$ , ${}^{15}N$ ) ${}^{20}{Ne}$ at 46-, 58-, and 68-MeV incident energy. It provides evidence for a two-step process. This result was expected for structural and kinematical reasons.
