Lifetimes of some high-spin states in the negative parity magnetic dipole band in 112Sb were determined using the Doppler-shift attenuation method. The deduced M1 transition rates show a small decrease with increasing spin. This decrease is reasonably accounted for within the framework of the tilted axis cranking (TAC) model. There also appears to be a considerable contribution from collective rotation. This is the first indication of such behavior in the A≈110 mass region, determined through lifetime measurements. The TAC calculations based on a πg9/2-1⊗νh11/2 configuration reproduce the magnetic dipole band.
