Structure of positive parity bands and observation of magnetic rotation in $^{108}$Ag

The interplay of nuclear forces among the neutron particles (holes) and proton holes (particles) in the odd-odd nuclei gives rise to a variety of shapes and hence novel modes of excitations. The odd-odd nuclei in the A $\sim$ 110 region have proton holes in the g$_{9/2}$ orbital and the neutron particles in the h$_{11/2}$ orbitals. A systematic study of shears mechanism in A $\sim$ 110 region indicates the presence of magnetic rotation (MR) phenomenon in Ag and In isotopes. Therefore, the structure of doubly odd $^{108}$Ag nucleus was probed in two different reactions, i.e, $^{100}$Mo($^{11}$B, 4n)$^{108}$Ag at 39 MeV and $^{94}$Zr($^{18}$O, p3n)$^{108}$Ag at 72 MeV beam energies. The emitted $\gamma $-rays were detected using the Indian National Gamma Array (INGA) at TIFR, Mumbai. A significant number of new transitions and energy levels were identified [1]. Lifetime measurements, using the Doppler shift attenuation method, have been carried out for a positive parity dipole band. Tilted Axis Cranking (TAC) calculations have been performed for two positive parity dipole bands. \\[4pt] [1] J. Sethi, et al., Phys. Lett. B \textbf{725}, 85 (2013).
