Zr92(p→, α)Y89reaction at 17 MeV

Abstract

The differential cross sections and analyzing powers for the $^{92}\mathrm{Zr}(\stackrel{\ensuremath{\rightarrow}}{p}, \ensuremath{\alpha})^{89}\mathrm{Y}$ reaction have been measured at ${E}_{p}=17$ MeV. Distorted-wave Born approximation calculations, using both the cluster and three-nucleon microscopic form factors, have been performed for the first four states in $^{89}\mathrm{Y}$. An empirical normalization factor for the ($p, \ensuremath{\alpha}$) reaction has been obtained from the microscopic calculation of the ground state transition. Using this normalization factor, the spectroscopic factors for the other states have been obtained and these compare well with those obtained in the single proton pickup reactions.NUCLEAR REACTIONS $^{92}\mathrm{Zr}(\stackrel{\ensuremath{\rightarrow}}{p}, \ensuremath{\alpha})^{89}\mathrm{Y}$, ${E}_{p}=17$ MeV, measured $\ensuremath{\sigma}({E}_{\ensuremath{\alpha}}, \ensuremath{\theta})$ and $i{T}_{11}({E}_{\ensuremath{\alpha}}, \ensuremath{\theta})$, DWBA calculations, spectroscopic factors.
