本文讨论了在三维笛卡尔网格上波函数和势的数值表示的核含时Hartree-Fock计算中的角动量守恒。即使对于相对粗糙的空间网格，变形核的自由旋转也表现得非常好。重离子碰撞产生一个高激发的化合物系统，并伴随着大量的核子发射。这些发射的核子到达数值盒的边界，导致角动量的减少。我们讨论的策略，以区分物理合理的损失，从数字文物。
We discuss the conservation of angular momentum in nuclear time-dependent Hartree-Fock calculations for a numerical representation of wave functions and potentials on a three-dimensional Cartesian grid. Free rotation of a deformed nucleus performs extremely well even for relatively coarse spatial grids. Heavy ion collisions produce a highly excited compound system associated with substantial nucleon emission. These emitted nucleons reach the bounds of the numerical box which leads to a decrease of angular momentum. We discuss strategies to distinguish the physically justified loss from numerical artifacts.
