天体物理学相关能量的α粒子光学势证明

Alpha-particle optical potential proofs at astrophysically relevant energies

M. Avrigeanu, V. Avrigeanu

摘要:

$(α,γ)$和$(α$,n)最近测量的接近反应阈值的反应截面被先前开发的区域光学势很好地描述。因此,除了描述$α$-粒子弹性散射的参数在较高的能量下的库仑势垒的能量下的$α$-粒子的光学势的特定功能被确认。类似的统计模型计算较小的反应通道的其他限制被证明是最有可能由于被忽视的过程或封闭的核壳周围的统计模型参数的临界值。

英文摘要:

$(α,γ)$ and $(α$,n) reaction cross sections recently measured close to the reaction thresholds are rather well described by a previously developed regional optical potential. Thus, particular features of the $α$-particle optical potential at energies below the Coulomb barrier, besides parameters describing $α$-particle elastic scattering at higher energies are confirmed. Additional limitations of similar statistical model calculations for minor reaction channels are shown to be most likely due to an overlooked process or critical values of statistical model parameters around closed nuclear shells.
