Abstract

Abstract: Low-lying energy levels in the odd deformed nucleus 170Tm are studied by means of Coulomb excitation with heavy ions and by the 169Tm(d, p)170Tm reaction. The results are analysed in terms of the rotational model withassumption of two rotational K=1 and K=0 bands coupled by Coriolis interaction. The 150 keV splitting between the two bands is found to be predominantly due to the neutron-proton residual force. The sequence of levels in the ground state K=1 rotational band is proposed. As a part of this experiment, the Coulomb excitation of 170Yb has also been studied. The following members of the ground state rotational band are seen: 84(2+), 278(4+) and 567 keV (6+). The intrinsic quadrupole moment, Q0 (170Yb), obtained from this measurement is 7.40±0.40 b. The Q-value for the 169Tm(d, p)170Tm reaction is measured to be 4420±20 keV.
