Abstract

A charge-exchange threshold cusp is observed in the summed 160° excitation curve for ${}^{93}{Nb} (d, p) {}^{94}{Nb} (6^{+}, g . s . - 2^{+}, 0.31 MeV)$ at ∼7.1 MeV, the threshold of the analogous ${}^{93}{Nb} (d, n) {}^{94}{Mo}^{A} (6^{+}, 13.2 M e V - 2^{+}, 13.5 MeV)$ reaction. As predicted by theory, it is essentially identical in shape to the excitation curve previously measured for ${}^{90}{Zr} (d, p) {}^{91}{Zr} (d_{\frac{5}{2}}, g . s .)$ in the same energy region.
