Abstract

The effect of dynamic deformation degrees of freedom in subbarrier fusion is calculated numerically in the coupled-channel representation. In the ease we study, we find that the frozen approximation is quite accurate for low-lying collective vibrations. Perturbation theory based on the eikonal approximation is useful for excitation energies extending to the giant resonance frequencies, and it can be used to test the applicability of the frozen approximation. Giant resonances can give a significant contribution to the enhancement of subbarrier fusion.

Effect of multiphonon coupling on heavy-ion fusion
1993, Nuclear Physics, Section A
The effect of the strong coupling of multiphonon states on the fusion of heavy ions is discussed. The model (CCFUS) of Dasso and Landowne is reviewed and it is shown that it is possible to generalise this to multiphonon states comprised of identical phonons without greatly complicating the calculations. The effect of the muliphonon channels on the barrier distribution for fusion is discussed in detail. In particular, it is shown that for such a system, one barrier may be pulsed up to rather high energies. This high-energy barrier will be difficult to see in the fusion data but we show that it may have a significant effect on the large-angle elastic (or quasielastic) excitation functions.
Fusion and evaporation-residue cross sections in the 16,18O + 92Mo interactions
1993, Nuclear Physics, Section A
The fusion and evaporation-residue cross sections in the ^16,18O + ⁹²Mo interactions for laboratory beam energies between 50 and 65 MeV have been measured by the on-line γ-ray and off-line X-ray methods. The fusion cross sections below the Coulomb barrier are well reproduced by a dynamical surface vibration model, the evaporation-residue cross sections, by statistical-model calculations carried out with the evaporation code CASCADE. The same code is used to predict the evaporation-residue cross sections in the ^14,15O + ⁹²Mo interactions which involve radioactive ion beams.

Gamma-ray multiplicity distributions in 16O + 152Sm fusion near and below the Coulomb barrier
1991, Physics Letters B
We have studied γ-ray multiplicity distributions for the system ¹⁶O + ¹⁵²Sm at five beam energies in the range 60–80 MeV, near and below the Coulomb barrier. The data were obtained using a large array of γ-ray detectors and an efficient evaporation-residue detector system utilizing an electrostatic deflector. The data are in good agreement with predictions of angular momentum distributions calculated using a coupled-channels model incorporating the effects of deformation.
Dynamical decay of a hot nucleus
1988, Physics Letters B
Particle decay from a hot compound nucleus is investigated concerning the effects of the coupling to low-lying vibrations and the primary excitation of the residual nucleus. They strongly affect the energy spectrum at low energies. The peak of the spectrum is shifted to a lower energy compared with that of the conventional statistical model. The thermal fluctuation of nuclear surface amplifies the dynamical effects.
