The coulomb excitation of Tb/sup 159/, Ho/sup 165/, and Tm/sup 169/ was studied using principally 60-Mev O/sup 16/ ions as projectiles. Both gamma ray and conversion electron spectra were taken. Rotational bands observed at 514 and 687 kev in Ho/sup 165/, at 580 (and possibly approximately 1280) kev in Tb/ sup 159/ and at 570 (and possibly approximately 1170) kev in Tm/sup 169/ were assigned as collective (gamma vibrational) bands. The bands at 361 kev in Ho/sup 165/, at 348 and 971 kev in Tb/sup 159/ and at approximately 900 kev in Tm /sup 169/ are ascribed to intrinsic (Nilsson) configurations. The properties of these bands are discussed in some detail. By multiple excitation 6 or 8 members of each ground state rotational band were excited. The analysis of the energies of these levels indicates the presence of higherorder Coriolis terms in the rotational energy formula in the cases Tb/sup 159/ and Tm/sup 169/. (auth)
