关联对高能中子-核总截面的影响

Effects of correlations on the total neutron-Nucleus cross section at high energies

摘要:

在考虑核子-核子关联、Glauber多重散射和非弹性阴影修正的情况下,计算了中子-核总截面。核靶从4 He到208 Pb,中子入射动量从3到300 GeV/c。相关性已被引入两种不同的方法,导致相同的结果。对常用的近似方法,即只用一体密度的乘积来处理核效应的近似方法进行了仔细的分析,结果表明,现代核子-核子相互作用产生的现实关联和现实核子-核子相互作用产生的现实关联以及核性质的微观基态计算的现实关联的影响是不可忽视的。

英文摘要:

The total neutron-Nucleus cross section has been calculated within an approach which takes into account nucleon-nucleon correlations, Glauber multiple scattering and inelastic shadowing corrections. Nuclear targets ranging from 4He to 208Pb and neutron incident momentum ranging from 3 to 300 GeV/c, have been considered. Correlations have been introduced by two different approaches leading to the same results. The commonly used approximation, consisting in treating nuclear effects only by a product of one-body densities, is carefully analyzed and it is shown that the effects of realistic correlations resulting from modern nucleon-nucleon interactions and realistic correlations resulting from realistic nucleon-nucleon interactions and microscopic ground state calculation of nuclear properties cannot be disregarded.
