关于低激发能核参数可靠值的实验测定问题--以Ni-60为例

On problems of experimental determination of reliable values of nucleus parameters at low excitation energy - Ni-60 as an example

A. M. Sukhovoj, V. A. Khitrov

摘要:

对已发表的Co-59(p,2 γ)Ni-60反应的实验数据进行了重新分析。确定了级联γ跃迁的能级密度和辐射强度函数的最可几值区域。所获得的数据由V.M. Strutinsky模型和半唯象模型-强度函数。确定了蒸发谱中核子发射截面的传统分析方法中出现最大误差的区域和最大误差的大小。第一次有系统地获得正确的信息的辐射强度函数的主要伽玛跃迁的中子结合能与平均超过大的初始水平。

英文摘要:

The reanalysis of the published experimental data from reaction Co-59(p,2gamma)Ni-60 was performed. The region of the most probable values of level density and radiative strength functions of cascade gamma-transitions was determined. The obtained data were rather precisely approximated by the V.M. Strutinsky model and semi-phenomenological model - for strength functions. The region of appearance and magnitude of maximal errors of the calculated cross-section of nucleon emission in evaporation spectra in traditional methods of their analysis were determined as well. There was for the first time obtained methodically correct information on the radiation strength function of primary gamma-transitions in diapason of neutron binding energy with averaging over large set of initial levels.
