Description
There are four proton holes and a number of neutron particles lie in the upper part of the g 9/2 proton orbital and in the middle part of the d 5/2, g 7/2 neutron orbital respectively in Pd nuclei. A number of rotational bands based on quasi neutron particles, antimagnetic rotational bands associated with proton holes and neutron particles were reported in 100,101,104Pd nucleus [1,2,3,4]. In previous study of Ref. [1], Band 9 was reported with a few gamma transitions without spin and parity assignment. Few levels of bands 5 and 6 were also reported without spin and parity assignments. To know the structure of a band, confirmation of spin and parity is necessary. In order to confirm the spin and parity of these states an experiment has been carried out via 94 Zr(13 C, 3n) reaction at beam energy 55 MeV with 15UD pelletron accelerator facility [5,6] of Inter University Accelerator Centre (IUAC), New Delhi. The target was ~1mg/cm 2 thick and ~10mg/cm2 thick 197 Au backing. The emitted gamma rays were detected by using 18 clover detectors at angles 32^0 , 57^0 , 90^0 , 123^0 , 148^0 of beam direction at Indian National Gamma Array (INGA) [7]. The multipolarities of few states of these two bands have been confirmed on the basis of R_DCO ratios. These results will be helpful for confirming the spin of several levels of 104 Pd nucleus. New results will be discussed during the conference.
