摘　　要：Band structure of the Z=104 nucleus256Rf has been a recent research focus in nuclear physics.We performed projected shell model calculations for this and some other neighboring Rf isotopes.Specifically,we studied rotational properties of these nuclei and showed that variations in dynamic moment of inertia were sensitive to single-particle structures,which may be useful information for locating the anticipated island of stability.Electromagnetic transition properties were also calculated,and measurable quantities were predicted for further experimental test.Band structure of the Z = 104 nucleus 256Rf has been a recent research focus in nuclear physics.
