摘要:

本文对中子共振的某些能量区间上平均的初级γ跃迁实验数据进行了重新分析。它们的累积和的近似与外推得到的分布到零值,使我们能够确定平均强度的E1-和M1-过渡,其可能的数量和总的分散强度偏离平均值。以这种方式确定的辐射强度函数的水平密度和总和证实了这些核参数的主要特点,从两步伽马级联的强度确定。

英文摘要:

Re-analysis of experimental data on primary gamma-transitions averaged over some energy intervals of neutron resonances has been performed. Approximation of their cumulative sums together with extrapolation of the obtained distribution to zero value allowed us to determine mean intensities of of E1- and M1-transitions, their probable number and total dispersion of intensity deviations from the mean value. The level density and sum of radiative strength functions determined in this way confirm main peculiarities of these nuclear parameters determined from intensities of the two-step gamma-cascades.
