Abstract：
The relation between α-backbending, nucleon-nucleon correlation and deformation in nuclei has been discussed. In general the backbending phenomena in gauge space are related to shape transition, however α-backbending is not only related to the quadrupole shape transition, but also related to other kinds of shape transition. The α-backbending phenomena also depend on the competition between n-p correlation and pair correlation, i.e., n-n and p-p correlation. The change of nuclear deformation with increasing nucleon number can be fundamentally described by unified shell model.
