Alpha-Transfer Reactions with Large Energy Transfers

Abstract

Alpha-transfer reactions ($^{20}\mathrm{Ne}$, $^{16}\mathrm{O}$), ($^{14}\mathrm{N}$, $^{10}\mathrm{B}$), and ($^{13}\mathrm{C}$, $^{9}\mathrm{Be}$) on a $^{40}\mathrm{Ca}$ target were studied at 262, 153, and 149 MeV, respectively. Analysis in terms of the direction-reaction theory reproduced the observed continuum spectra and angular distributions well, except for the cross section of the reaction ($^{20}\mathrm{Ne}$, $^{16}\mathrm{O}$) at small angles, which is attributed to a projectile breakup process.
