Abstract : The Coulomb excitation of Tm169 was studied using oxygen ions of energies up to 44 MeV as bombarding particles. De-excitation gamma rays were recorded in coincidence with back-scattered particles. The cascade/ crossover branching ratios in the decay of the rotational levels of the K = 1/2 band are compared with the predictions of the rotation model. It is found that, within experimental errors, a single set of rotational parameters g sub r, g sub k, b sub 0 and Q sub 0 describes all electromagnetic properties of the ground state band. Transitions assigned to gamma vibrational bands with K sub 1= K sub 0 =2 were also observed. (Author)
