Compound System Formation atEc.m.=36MeV inN14+C12→Li6+Ne20

Abstract

Angular distributions of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ produced in the reaction ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ + ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ → ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ + ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ have been measured at a center-of-mass energy of 36 MeV. Data were taken for the reactions ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$(${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$, ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$)${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ and ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$(${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$)${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ in order to cover the complete angular range (${16}^{\circ }<~{\theta }_{\mathrm{c}.\mathrm{m}.\mathrm{}}<~{165}^{\circ }$). The angular distributions are symmetric about ${\theta }_{\mathrm{c}.\mathrm{m}.\mathrm{}}={90}^{\circ }$ and closely follow a ${\left(sin\theta \right)}^{-1\mathrm{}}$ dependence. This is interpreted as indicating that the reaction proceeds primarily through compound-nucleus formation.
