( 3 ) . there exists a deficiency of the axial symmetry rotor plus two quasi - particles model for odd odd nuclei that the vibration far away from the inversion point is smaller
2.
( 2 ) . the calculations further confirm that the competion between the coriolis force and n - p coupling interaction in the low k space might be the possible dominating mechanism for si in odd odd nuclei
3.
According to the off - line rnb ' s requirement of the radioactive isotope , the doubly odd nucleus 64cu produced by reactor was chosen as the first nuclide to carry out expermental research about the off - line rnb
4.
We could draw an elementary conclusion : triaxial shape plays an important role to cause si in odd odd nuclei and its influence will become stronger in some nuclei which have 100 126 large g deformation , such as rh and la . ( 4 )
5.
Since the magic number 28 , which is the first that requires the introduction of a strong spin - orbit interaction belongs to the if2p shell in the nuclear shell model . so the nuclei in the if2p shell have been a research hotspot in nuclear physics . the doubly odd nucleus 64cu which is also in the if2p shell has been the subject of many experimental investigations previously via various type of nuclear reaction such as 64ni ( p , ny ) and its excitation leveles have been already studied to about 8 mev

In this paper , we first introduce the basic background of the study of nuclear structure , some elementary knowledge about and the latest achievements in the study of the phenomena of signature inversion ( si ) . then the description of the two quasi - particles plus a rotor model ( prm ) of odd odd nuclei is given . by the model we perform the practical calculations of the yrast bands of some nuclei in a 100 , 130 mass region
