Heavy ion radiative capture cross sections

Abstract

Cross sections for the radiative capture and one nucleon emission reactions have been obtained by mass identification of reaction products at 0\ifmmode^\circ\else\textdegree\fi{} using thin targets for the systems $^{12}\mathrm{C}$ + $^{14}\mathrm{N}$ (70 and 59 MeV), $^{30}\mathrm{Si}$ + $^{14}\mathrm{N}$ (70 and 59 MeV) and $^{27}\mathrm{Al}$ + $^{14}\mathrm{N}$ (59 MeV). The cross sections for radiative capture are in all cases 500 nb. The measurement of the $^{30}\mathrm{Si}$ + $^{14}\mathrm{N}$ cross section is in disagreement with previous work performed using thick targets. This discrepancy is discussed.NUCLEAR REACTIONS $^{12}\mathrm{C}$ + $^{14}\mathrm{N}$ (70 and 59 MeV), $^{30}\mathrm{Si}$ + $^{14}\mathrm{N}$ (70 and 59 MeV), $^{27}\mathrm{Al}$ + $^{14}\mathrm{N}$ (59 MeV) upper limits radiative capture cross sections + estimate of one nucleon emission cross section for $^{30}\mathrm{Si}$ + $^{14}\mathrm{N}$ (70 MeV).
