High-spin states were populated in {sup 108}Cd using the {sup 96}Zr({sup 16}O,4n) reaction at a beam energy of 72 MeV. Two magnetic dipole bands have been observed, both of which contain weak E2 crossover transitions. Lifetimes for the stronger of the two bands were measured via the Doppler shift attenuation method. The configuration assignment for this band has been determined from comparison with tilted axis cranking model calculations to be {pi}[g{sub 9/2}{sup -3}g{sub 7/2}](multiply-in-circle sign){nu}[h{sub 11/2}(g{sub 7/2}d{sub 5/2}){sup 1}] and {pi}[g{sub 9/2}{sup -3}g{sub 7/2}](multiply-in-circle sign){nu}[h{sub 11/2}{sup 3}(g{sub 7/2}d{sub 5/2}){sup 1}], before and after the {nu}h{sub 11/2}{sup 2} band crossing, respectively. The deduced B(M1) strengths decrease rapidly with increasing spin after the {nu}h{sub 11/2}{sup 2} alignment, which is a characteristic behavior of a shears band.
