Same as Fig. 1,but depicting the variations of the extracted α-particle preformation factors (left) and two-neutron separation energy gap (right) against the neutron number for Rn, Ra and Th isotopes.

Caption

Microscopically, the preformation factors extracted by the model and the calculated two-neutron separation energy gap also show the magic changes when N = 126. This means that the neutron magic number is an important probe to investigate the nuclear structure.  At present, there are relatively few studies on the nuclear structures in the heavy and superheavy region, especially near the possible sub-magic numbers N=152 and magic numbers N=162. This is very important for the synthesis of new elements in the future.
