标题： Improvement of the nucleon emission process and the statistical property in molecular dynamics

摘要： 我们提出在分子动力学中引入一个新的随机过程，以改善对热核中核子发射过程的描述。 我们在核子从原子核中发射时，将其动量波动来源于核子波包的动量宽度，以随机方式赋予核子。 我们通过计算反对称分子动力学情况下的液气相平衡，表明通过这一改进，我们可以恢复核子粒子发射过程中的量子力学统计性质。 显示英文摘要

摘要： We propose to introduce a new stochastic process in molecular dynamics in order to improve the description of the nucleon emission process from a hot nucleus. We give momentum fluctuations originating from the momentum width of the nucleon wave packet to the nucleon stochastically when it is being emitted from the nucleus. We show by calculating the liquid gas phase equilibrium in the case of antisymmetrized molecular dynamics, that with this improvement, we can recover the quantum mechanical statistical property of the nucleus for the particle emission process.
