Abstract

In the reaction ${}^{12}C (e, e^{'} d) {}^{10}B$ the lowest-lying $T = 1$ state in ${}^{10}B$ is found to be as strongly excited as the $T = 0$ ground state of ${}^{10}B$ , although the transition to the $T = 1$ state is isospin forbidden for direct deuteron knockout. A mechanism integration of a $p - n$ pair in a relative $T = 1$ state into a deuteron is proposed to explain this result. This new proposed mechanism is consistent with both the observed purely transverse character of the transition and the momentum-transfer dependence of the cross section.
