High spin states of {sup 107}In have been investigated using the reaction {sup 94}Mo({sup 16}O,p2n){sup 107}In at a beam energy of 70 MeV. A total of 62 new gamma transitions have been placed in the level scheme and several DELTAI=1 sequences and one DELTAI=2 sequence have been found. Lifetime measurements using the Doppler-shift attenuation method (DSAM) have been carried out for band states of DELTAI=1 and DELTAI=2. A decreasing trend of B(M1) strengths with increasing spin deduced for the DELTAI=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 DELTAI=2 band has been found to be a deformed band with beta{sub 2}approx0.2.
