“…The reduced DWBA cross sections dσ i /d DW were calculated using DWUCK-4 with a macroscopic form factor. For both 184 W and 186 W the transitions to the ground state band states 2 + , 4 + and 6 + have been calculated from equation (1) with β 2 = 0.265 (Kruse et al 1971), β 4 = −0.095 and β 6 = 0.01 (Moller et al 1995). For simplicity the full strength of the transitions to the member states of the γ -band (K = 2) and of the K = 2 and K = 5 configurational bands (Firestone 1989) has been located in the first excited states of these bands.…”

Pre-equilibrium neutron emission includes substantial collective excitations in the continuum region that add to the multistep direct and multistep compound reactions. These collective reactions are investigated for the strongly-deformed, rotational tungsten nucleus. The collective cross sections are calculated using the macroscopic model. The results describe the neutron emission cross sections measured at 14.1 MeV and 26 MeV incident neutron energy.

“…(The value of β 20 is not determined from the SRM level structure analysis). The β 20 value was determined by reproducing the measured data of proton-induced direct inelastic scattering differential cross sections of the first 2 + level excitation [28] with the CC computation. The SRM-CC calculation was done with the OPTMAN code [27].…”

The 150 Sm(n,n′γ) reaction was measured from E n = 1 to 15 MeV at the Los Alamos Neutron Science Cemter (LANSCE). The γ rays were detected with the Compton-suppressed Germanium Array for Neutron Induced Excitations (GEANIE). Measured γ-ray excitation functions were converted to partial γ-ray cross sections, Twenty four individual γ-rays up to E x = 1.8 MeV in 150 Sm were measured. Results are compared with enhanced Hauser Feshbach model calculations: the spin distribution in the pre-equilibrium reaction is calculated with the quantum mechanical model of Feshbach, Kerman and Koonin. The particle transmission coefficients were calculated with two different global optical model potential parameter sets. We employed the coupled-channel optical model based on the soft rotor model and with spherical potential.

“…Figure 6. Same as figure4, but for 186 W and 183 W, compared with the experimental data[4,7,63,66]. The label '(p, p)+(p, p )' implies the sum of elastic and inelastic scattering angular distributions of the first, second, third, fourth and fifth excited states.…”

Nucleon scattering on tungsten and neighboring nuclei are analyzed with a coupled-channels method based on a soft-rotator structure model. The multiple band couplings and nuclear stretching factors are built using nuclear wave functions of the soft-rotator model with the Hamiltonian parameters adjusted to reproduce the energy of low-lying collective levels of corresponding nuclei. A regional lane-consistent dispersive coupled-channels optical-model potential is derived to reproduce the neutron total cross sections, nucleon elastic and inelastic scattering angular distributions, and analyzing powers. Excellent agreement with measurements is obtained for neutron total cross sections of 182,183,184,186W, 178Hf, and 181Ta targets in the whole energy range from 100 keV to 200 MeV; other scattering data are found to be in good agreement with measurements. A deformation-dependent nuclear radius correction arising from the volume conservation condition is introduced and allowed to remove phenomenological radii dependencies on nuclear mass from the potential geometry.
