ON THE MECHANISM OF BACKBENDING PHENOMENA OF SOME EVEN-EVEN NUCLEI

  • The energy levels, B(E2) values and gyromagnetic ratio g of some even-even nuclei have been calculated with a double band scheme of band-crossing. Based on these results, the mechanism of backbending phenomena is analyzed, and the possible criterion to distinguish the effects of shape transition, rotation-alignment and pairing collapse are also discussed.

ON THE MECHANISM OF BACKBENDING PHENOMENA OF SOME EVEN-EVEN NUCLEI

Abstract: The energy levels, B(E2) values and gyromagnetic ratio g of some even-even nuclei have been calculated with a double band scheme of band-crossing. Based on these results, the mechanism of backbending phenomena is analyzed, and the possible criterion to distinguish the effects of shape transition, rotation-alignment and pairing collapse are also discussed.
