alpha particle momentum distributions from 12C decaying resonances
摘要：
计算的$α$粒子动量分布从低位的$^{12}$ C共振的衰减。用复标度超球绝热膨胀法计算了衰变碎片的波函数。波函数的大距离部分是至关重要的，必须精确计算。我们讨论了$^{12}$ C的$4^+$、$1^+$和$4^-$态的能量分布、角分布和Dalitz图。
英文摘要：
The computed $α$ particle momentum distributions from the decay of low-lying $^{12}$C resonances are shown. The wave function of the decaying fragments is computed by means of the complex scaled hyperspherical adiabatic expansion method. The large-distance part of the wave functions is crucial and has to be accurately calculated. We discuss energy distributions, angular distributions and Dalitz plots for the $4^+$, $1^+$ and $4^-$ states of $^{12}$C.
