Abstract: (APS)
High spin states of In107 have been investigated using the reaction Mo94(O16,p2n)In107 at a beam energy of 70 MeV. A total of 62 new γ transitions have been placed in the level scheme and several ΔI=1 sequences and one ΔI=2 sequence have been found. Lifetime measurements using the Doppler-shift attenuation method (DSAM) have been carried out for band states of ΔI=1 and ΔI=2. A decreasing trend of B(M1) strengths with increasing spin deduced for the ΔI=1 band indicates the presence of a shears mechanism. The experimental data for this band are compared with the tilted axis cranking (TAC) calculations. The ΔI=2 band has been found to be a deformed band with β2~0.2.- 27.60.+j
