在质心和实验室系统中被非共振背景畸变的孤立复合共振附近的散射截面和持续时间
On scattering cross sections and durations near an isolated compound-resonance, distorted by the non-resonant background, in the center-of-mass and laboratory systems
摘要：
在过去的20年里，人们发现并发表了在化合物-核共振区（在质心（C-）系统中），由于非共振背景的畸变，时间提前而不是时间延迟的现象。这种现象通常伴随着在相同能量附近的截面中的最小值。本文分析了实验室（L-）系统中核子-核散射的截面和时间延迟。在L-系统中不出现延迟-超前现象。我们使用和具体化的非标准的解析变换的截面从C-系统的L-系统，在我们以前的文件中获得。通过对~（12）C、~（16）O、~（28）Si、~（52）Cr、~（56）Fe和~（64）Ni等核在畸变共振范围内的核子弹性散射的L系统截面的能量依赖关系的计算，并与实验数据进行了比较，说明了上述结果的正确性。
英文摘要：
During last 20 years there was revealed and published the phenomenon of the appearing of the time advance instead of the time delay at the region of a compound-nucleus resonance, distorted by the non-resonant background (in the center-of-mass (C-) system). This phenomenon is usually accompanied by a minimum in the cross section near the same energy. Here we analyze the cross section and the time delay of the nucleon-nucleus scattering in the laboratory (L-) system. In the L-system the delay-advance phenomenon does not appear. We use and concretize the non-standard analytical transformations of the cross section from the C-system to the L-system, obtained in our previous papers. They are illustrated by the calculations of energy dependences of cross sections in the L-system for several cases of nucleon elastic scattering by nuclei 12C, 16O, 28Si, 52Cr, 56Fe and 64Ni at the range of distorted resonances in comparison with the experimental data.
