Laser诱导的μ原子非共振核激发
Laser-induced nonresonant nuclear excitation in muonic atoms
摘要：
计算了强激光驱动μ子原子的相干核激发。这种核跃迁是由束缚μ子振荡电荷密度的含时库仑场引起的。电多极跃迁的封闭形式的解析表达式推导和适用于各种同位素的激发概率一般都很小。通过与原子壳层的耦合，比较了这一过程与其他核激发机制的异同，并讨论了在实验上观察这一过程的前景。
英文摘要：
Coherent nuclear excitation in strongly laser-driven muonic atoms is calculated. The nuclear transition is caused by the time-dependent Coulomb field of the oscillating charge density of the bound muon. A closed-form analytical expression for electric multipole transitions is derived and applied to various isotopes; the excitation probabilities are in general very small. We compare the process with other nuclear excitation mechanisms through coupling with atomic shells and discuss the prospects to observe it in experiment.
