We present an experimental study of the laser-induced luminescence spectra of Mn atoms in solid helium matrices. We observe transitions of the valence electron and of inner-shell electrons. We find that the Mn-He interaction perturbs the inner-shell transitions to a lesser extent than the valence-electron transitions. The observed lineshapes of the inner-shell transitions of Mn are similar to those of an inner-shell transition in Ba studied earlier. At the same time, they are more strongly perturbed than the corresponding transitions in Au and Cu under the same conditions. We suggest a qualitative explanation of these observations based on the atomic bubble model. Our results also suggest that the inner-shell transitions of Mn in solid He are more strongly perturbed than the same lines of Mn isolated in solid Ar or Kr matrices.
我们展示了对固态氦基质中锰原子激光诱导发光光谱的实验研究。我们观察到了价电子和内壳层电子的跃迁。我们发现，锰 - 氦相互作用对内壳层跃迁的扰动程度小于对价电子跃迁的扰动程度。所观察到的锰内壳层跃迁的线形与先前研究的钡内壳层跃迁的线形相似。同时，在相同条件下，它们比金和铜中的相应跃迁受到的扰动更强。我们基于原子气泡模型对这些观察结果提出了定性解释。我们的结果还表明，固态氦中锰的内壳层跃迁比孤立于固态氩或氪基质中的锰的相同谱线受到的扰动更强。
