论文摘要
我们分析了$^{16} {\ rm c}+p $和$^{16} {\ rm c}+d $ reactions在四体和五体连续性contionum contionum contionumed contected Channel（CDCC）方法中。 $^{16} $ c核由$^{14} {\ rm c}+n+n $ n $配置中的超球坐标。此说明重现了相当不错的几个$^{16} $ c低洼状态。首先，我们分析$ 2^+\ rightarrow 0^+$ $ $ e2 $过渡幅度，该振幅确认必须引入有效的费用以重现实验价值。然后，通过包括$^{16} $ c pseudostates来研究质子和Deuteron弹性和非弹性散射，该蛋白质模拟$^{14} {\ rm c}+n+n $ continuum。在$^{16} {\ rm c}+D $中，将deuteron分解用$ p+n $两体伪固定剂考虑在内。在没有任何拟合参数的情况下获得了与实验的公平协议。分解效应通常很小，但可以改善与实验的一致性。
We analyze the $^{16}{\rm C}+p$ and $^{16}{\rm C}+d$ reactions within the four- and five-body Continuum Discretized Coupled Channel (CDCC) method. The $^{16}$C nucleus is described by a $^{14}{\rm C}+n+n$ configuration in hyperspherical coordinates. This description reproduces fairly well several $^{16}$C low-lying states. First we analyze the $2^+\rightarrow 0^+$ $E2$ transition amplitude, which confirms that an effective charge must be introduced to reproduce the experimental value. Then, proton and deuteron elastic and inelastic scattering are investigated by including $^{16}$C pseudostates, which simulate the $^{14}{\rm C}+n+n$ continuum. In $^{16}{\rm C}+d$, the deuteron breakup is taken into account with $p+n$ two-body pseudostates. A fair agreement with experiment is obtained without any fitting parameter. Breakup effects are in general small, but improve the agreement with experiment.
