结构化学中可观测物理量的确定值与平均值

以类氢原子轨道的组合态为体系,分析了能量和轨道角动量具有确定值的条件。并结合实例讨论了非本征态下的位置、能量和轨道角动量平均值的计算中容易出现的若干问题。

The Definite Values and Average Values of Physical Observables

For systems with state formed from the combination of hydrogen-like orbitals, the conditions for having definite values of physical observables such as energy and angular momentum have been analyzed. Several problems are also discussed in finding average values of position, energy and angular momentum for non-eigenstates.
