(p, d), (p, t), and (p, α) Reactions to the Same Final States inFe56and inZr90

Abstract

The reactions ${\mathrm{Fe}}^{57}(p, d)$, ${\mathrm{Fe}}^{58}(p, t)$, and ${\mathrm{Co}}^{59}(p, \alpha )$, all exciting final states in ${\mathrm{Fe}}^{56}$, and the reactions ${\mathrm{Zr}}^{91}(p, d)$, ${\mathrm{Zr}}^{92}(p, t)$, and ${\mathrm{Nb}}^{93}(p, \alpha )$, all exciting final states in ${\mathrm{Zr}}^{90}$, were studied with 22-MeV protons from the ORNL 86-in. Cyclotron. The angular distributions and cross sections for each of these reactions exciting the same final states were obtained. The cross sections for exciting a given final state by each of the reactions provides an indication of the relative probability for the single, double, and triple pickup process.
