Staggering Effects in Nuclear and Molecular Spectra

摘要: It is shown that the recently observed ΔJ=2 staggering effect (i.e. relative displacement of levels with angular momenta J, J+4, J+8,…, relatively to J+2, J+6, J+10, …) seen in superdeformed nuclear bands also occurring certain electronically excited rotational diatomic molecules (YD, CrD, CrH, CoH), which it attributed interband interactions (bandcrossings). In addition, ΔJ=1 even momentum J respect same band odd J) studied molecular free from interactions/bandcrossings). Bands YD offer evidence for absence any due disparity masses, while sextet electronic states CrD demonstrate a sensitive probe deviations behaviour, this particular case spin-rotation and spin-spin interactions.
