摘要:

我们展示了相当有趣的表现形式的共存的共振特性的3d-电子在Xe@C60的光电离的特性。结果表明,由3D光子电离产生的光电子的反射极大地影响部分光电离截面和水平和各自的角各向异性参数,偶极和非偶极添加到所有这些额外的最大值和最小值。计算是将3/2和5/2电子视为不同类型的电子进行的,它们的自旋“向上”和“向下”。C60壳层的影响在“橙色”表皮势模型的框架下考虑。

英文摘要:

We demonstrate rather interesting manifestations of co-existence of resonance features in characteristics of the photoionization of 3d-electrons in Xe@C60. It is shown that the reflection of photoelectrons produced by the 3d Xe photoionization affects greatly partial photoionization cross-sections of and levels and respective angular anisotropy parameters, both dipole and non-dipole adding to all of them additional maximums and minimums. The calculations are performed treating the 3/2 and 5/2 electrons as electrons of different kinds with their spins "up" and "down". The effect of C60 shell is accounted for in the frame of the "orange" skin potential model.
