采用核乳胶方法研究二元解离过程,该过程导致每核子3.65 GeV的$^{16}$O核和每核子3.22 GeV的$^{22}$Ne核形成$\alpha$粒子。$^{16}$O$\to$$^{12}$C(0$^+_1$)+$\alpha$道的不变质量分布表明$^{16}$O(0$^+_6$)激发的衰变,其概率超过$^{12}$C(0$^+_2$)+$\alpha$道估计值的20倍。$^{22}$Ne$\to$$^{18}$O+$\alpha$道的不变质量分布显示出对应于约11.6 MeV的$^{22}$Ne激发的峰。
英文摘要
The nuclear emulsion method is applied to study binary dissociation leading to the formation of $α$-particles from $^{16}$O nuclei at 3.65 GeV per nucleon and $^{22}$Ne nuclei at 3.22 GeV per nucleon. The invariant mass distribution for the $^{16}$O$\to$$^{12}$C(0$^+_1$)+$α$ channel indicates decays of the $^{16}$O(0$^+_6$) excitation, whose probability exceeds the estimate for the $^{12}$C(0$^+_2$)+$α$ channel by a factor of 20. The invariant mass distribution for $^{22}$Ne$\to$$^{18}$O+$α$ exhibits a peak corresponding to $^{22}$Ne excitations around 11.6 MeV.
