Superdeformed and highly deformed bands in Zn-65 and neutron-proton interactions in Zn isotopes - art. no. 041301

Superdeformed and highly deformed rotational bands were established in Zn-6 5 using the Ca-40(Si-29,4p)Zn-65 reaction, and averaged quadrupole moments were measured for two of these bands. The configurations of these bands wer e assigned based on Hartree-Fock calculations. One of the three bands exhib its at low (h) over bar omega a rise in the J((2)) dynamic moments of inert ia that is similar to the alignment gain observed in Zn-60. A comparison of the rotational band configurations and their J((2)) moments of inertia for light Zn isotopes suggests that the rise in J((2)) is most likely caused b y np interactions associated with the valence protons and neutrons occupyin g the g(9/2) intruder orbits.
