High energy (He3,dproton stripping byAl27andSi28nuclei: Transitions to excited states

Angular distributions for the ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}({}_{}{}^3{}_{}{}^{}\mathrm{He}, d){}_{}{}^{28}{}_{}{}^{}\mathrm{Si}_{}^{*}{}_{}{}^{}$ and ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}({}_{}{}^3{}_{}{}^{}\mathrm{He}, d){}_{}{}^{29}{}_{}{}^{}\mathrm{P}_{}^{*}{}_{}{}^{}$ reactions have been measured at $E_{{}_{}{}^3{}_{}{}^{}\mathrm{He}}=130\mathrm{}$ MeV) in the angular range of $9°\lesssim {\theta }_{\mathrm{c}.\mathrm{m}.\mathrm{}}\lesssim 40°$. In the proton-unbound excitation energy region, four prominent peaks ($E_x=11.61, 12.67, 13.26, \mathrm{and} 14.33$ MeV) from the ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}({}_{}{}^3{}_{}{}^{}\mathrm{He}, d){}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$ reaction and three peaks ($E_x=6.59, 8.08, \mathrm{and} 10.17$ MeV) from the ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}({}_{}{}^3{}_{}{}^{}\mathrm{He}, d){}_{}{}^{29}{}_{}{}^{}\mathrm{P}$ reaction, are reported and analyzed for the first time. The data have been analyzed in terms of the DWBA theory, using optical model and other relevant parameters determined in a previous paper on the ground state transitions. In general, satisfactory fits to the experimental angular distributions are obtained. Spectroscopic information has been extracted and compared with the results available in the literature.
