Abstract

The isospin-forbidden reaction ${}^{12}C (d, α_{2}) {}^{10}B (1.74, T = 1)$ was investigated for $E_{d} = 14.0 to 17.0$ MeV. Several full angular distributions were obtained and the excitation function from $E_{d} = 16.0 to 17.0$ MeV was measured at $θ_{lab} = 152 °$ . In the light of these new data, it is clearly not sufficient to interpret the reaction in terms of simple compound-nucleus formation, as seemed to be indicated in previous investigations.
