摘要:

更好地理解原子核中短程关联所起的作用将大大有助于当前和未来的电子和中微子散射实验。两体物理学,包括核子-核子关联和两体电弱电流,需要解释静态和动态核性质的实验数据。在这项工作中,我们专注于研究核子-核子关联从手征有效场论的角度来看,并提供了一套全面的新的变分Monte Carlo计算的一个和两个身体的密度和动量分布的基础上的诺福克多体核哈密顿量为A<=12系统。可在线查阅详细的表格和数字。

英文摘要:

Current and future electron and neutrino scattering experiments will be greatly aided by a better understanding of the role played by short-range correlations in nuclei. Two-body physics, including nucleon-nucleon correlations and two-body electroweak currents, is required to explain the body of experimental data for both static and dynamical nuclear properties. In this work, we focus on examining nucleon-nucleon correlations from a chiral effective field theory perspective and provide a comprehensive set of new variational Monte Carlo calculations of one- and two-body densities and momentum distributions based on the Norfolk many-body nuclear Hamiltonians for A<=12 systems. Online access to detailed tables and figures is available.
