三体衰减多体共振的能量分布
Energy distributions from three-body decaying many-body resonances
摘要：
我们计算三个粒子的能量分布出现衰减多体共振。我们再现测量的能量分布从两个原型状态的衰变选择为最低的$0^{+}$和$1^{+}$ -共振在$^{12}$ C填充在$β$ -衰变。这些状态分别由通过$^{8}$ Be基态的顺序衰变和直接衰变主导。这些衰变机制反映在从小的、团簇或壳模型状态到大距离的“动态”演化中，在大距离中，坐标或动量空间连续波函数被精确计算。
英文摘要：
We compute energy distributions of three particles emerging from decaying many-body resonances. We reproduce the measured energy distributions from decays of two archetypal states chosen as the lowest $0^{+}$ and $1^{+}$-resonances in $^{12}$C populated in $β$-decays. These states are dominated by sequential, through the $^{8}$Be ground state, and direct decays, respectively. These decay mechanisms are reflected in the ``dynamic'' evolution from small, cluster or shell-model states, to large distances, where the coordinate or momentum space continuum wavefunctions are accurately computed.
