“…Such a small value for ~el implies that 7 emission becomes important only when particle decay is energetically forbidden. In agreement with the results of many previous works [29][30][31] such values for the two parameters lead to the prediction of too many evaporated neutrons. For example, the maximum of the calculated 4n excitation function is shifted by ~ 5 MeV towards lower energy compared to the experimental data.…”

Evaporation residue excitation functions and statistical 7-ray spectra have been measured in the heavy ion fusion reaction ~60+144Nd~16~ between EL~b=76 and 105 MeV. In agreement with statistical model calculations, the evolution of the 7-ray spectra as a function of the compound nucleus excitation energy is consistent with the emission of high-energy ~ rays (E~> 10 MeV) in the early stage of the decay process. The description of the evaporation residue distributions by the statistical model is improved if a 7 strength function including a giant dipole resonance built on each excited state and describing the shape of the measured statistical 7-ray spectra is used in the calculations. The present analysis shows, however, that there is a strong correlation between the parameters of the resonance deduced from the fit to the 7-ray spectra and other parameters of the statistical model, in particular the level density parameter.

“…The low lying odd parity yrast states in 153 Ho is reported [28] to arise from the coupling of h 11/2 proton to the yrast 2 + , 4 + , 6 + , 8 + states, probably of configuration ν(h 9/2 f 7/2 ), in 152 Dy. Similarly for 157 Lu [29], the observed level structure is almost identical with that of 156 Yb [30], upto spin 12 + .…”

“…High-spin states in 155 Yb were populated by using the fusion-evaporation reaction 144 The target consisted of a 2.89 mg/cm 2 144 Sm metallic foil with a 13.13 mg/cm 2 Pb backing. The in-beam γ rays were measured with the AFRODITE array [19], which consists of eight Compton suppressed clover detectors at the time of the experiment.…”

“…For the eveneven Yb isotopes, the low-lying excitations exhibit a clear structural evolution with neutron number N . For instance, with N decreasing from 88 to 84, 158 Yb shows the behavior of soft rotation [1]; 156 Yb undergoes an evolution from a quasivibrational to quasirotational structure with increasing spin [2,3]; and 154 Yb is interpreted in terms of the quasiparticle coupling [4,5]. For the odd-A Yb isotopes in this transitional region, collective structures built on the f 7/2 , h 9/2 , and i 13/2 neutron orbitals have been observed in 157 Yb [6,7] and the coexistence of different nuclear shapes has been revealed.…”

High-spin states in 155 Yb have been studied via the 144 Sm( 16 O ,5n) 155 Yb reaction at a beam energy of 118 MeV. One negative-parity and one positive-parity cascade built on the νf 7/2 and νi 13/2 states, respectively, are established for the first time. The structures observed in 155 Yb are compared with those in the neighboring N = 85 isotones and with semiempirical shell-model (SESM) calculations. According to adiabatic and configuration-fixed constrained triaxial covariant density functional theory (CDFT) calculations, a coexistence of prolate and oblate shapes is predicted to exist in 155 Yb.
