الوصف: Excited states of $$^{109}\hbox {Ag}$$ have been investigated by in-beam $$\gamma $$ -ray spectroscopic techniques using the $$^{110}\hbox {Pd}$$ ( $$^{7}\hbox {Li}$$ , $$\alpha 4\hbox {n}$$ ) $$^{109}\hbox {Ag}$$ reaction at a beam energy of 46 MeV. The level scheme of $$^{109}\hbox {Ag}$$ is significantly extended with the addition of more than 20 new $$\gamma $$ transitions. For the positive-parity yrast band, it is extended to $$41/2^{+}$$ state and $$2\hbar $$ higher than the earlier work. A negative-parity band decaying to the yrast band by eleven new linking transitions is identified, and several E2 crossover transitions of this band are observed, thereby confirming the spin-parity assignment and the ordering of dipole transitions above the $$I^{\pi } = 17/2^{-}$$ level. Experimental total angular momenta, kinematical and dynamical moments of inertia, and B(M1)/B(E2) ratio for the negative-parity band are compared with the predictions of self-consistent titled axis cranking relativistic mean-field model. Based on the theoretical description and the observed characteristics, the negative-parity dipole band is suggested as a magnetic rotational band arising from shears mechanism.
