Abstract

Coupled-channels calculations of the collision of ¹⁶O with ¹⁵⁴Sm are performed with strong and weak absorptive potentials. In the former, the polarization tensors t_2q of inelastically scattered projectiles are seen to follow the shape-effect relations while in the latter, strong deviations from these shape relations are observed. It is shown that the adiabatic model, where the centrifugal potentials in different channels are approximated by that corresponding to the total angular momentum, J, is able to reproduce these features. The isocentrifugal approximation which uses an average orbital angular momentum fails to reproduce the deviations. Comparison between the two adiabatic models is presented. We also show how corrections for Coriolis effects may be made.

Barrier distributions from elastic scattering
1996, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
A new representation of the distribution of potential barriers present in heavy-ion reactions is defined in terms of the elastic scattering excitation function. Its validity is demonstrated for the systems ¹⁶O + ^144.154Sm, ¹⁸⁶W, ²⁰⁸Pb, for which precise measurements have been made. Compared with fusion barrier distributions, which show structures characteristic of collective inelastic couplings, the elastic distributions are less detailed. This appears to be due to couplings to weaker direct-reaction channels.
Probing fusion barrier distributions with quasi-elastic scattering
1995, Nuclear Physics, Section A
Excitation functions have been measured for quasi-elastic back-scattering of ¹⁶O on ⁹²Zr, ¹⁴⁴Sm, ¹⁵⁴Sm and ¹⁸⁶W targets. A new procedure to extract representations of fusion barrier distributions is suggested and applied. The results are compared with barrier distributions obtained from fusion data and with coupled-channel calculations. The representations from quasi-elastic scattering are consistent with those from fusion below the average barrier energy. However, the effect of transfer smooths the quasi-elastic representations at higher energies, so that the sensitivity to the barrier distribution is reduced.
Algebraic rotating-frame approach to nuclear reactions
1994, Nuclear Physics, Section A
An approach to nuclear reactions is discussed in which the rotating-frame approximation is combined with an algebraic model of the nuclear collective states, the interacting-boson model. The coupled multi-channel problem reduces to that of single-channel potential scattering with a fluctuating potential, whose strength is characterized by a finite set of values. Several versions of the rotating-frame approximation are compared with an exact coupled-channel calculation for the inelastic scattering of an α-particle from ¹⁵⁴Sm. It is shown that an appropriate choice of the version used, together with a proper normalization of the coupling strength, leads to a significant improvement upon the conventional form of this approximation when Coulomb excitation is included.
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.
Nuclear physics with polarized heavy ions
1992, Physics Reports
Polarized heavy ion beams (⁶Li, ⁷Li, ²³Na) have been in use as tools for the investigation of nuclear scattering and nuclear reactions for almost two decades. This review attempts to survey the research activities in this field with reference to nuclear structure, nuclear dynamics and reaction mechanisms. Besides reviewing the results from full quantum mechanical coupled channels analyses of data, special attention is paid to handwaving arguments and semiclassical pictures as a complementary way of obtaining a better understanding of the relevant physics.
A geometric approach to strong coupling effects in heavy-ion collisions. Deviation from the Fresnel diffraction pattern
1991, Physics Letters B
We offer a novel interpretation of the deviation of the experimental angular distribution for elastic ¹⁸O+¹⁸⁴W scattering at 90 MeV from the standard Fresnel diffraction pattern in terms of an interference between scattering amplitudes corresponding to different orientations of the target nucleus. The importance of Coriolis coupling, which is initially neglected in this geometric approach, is discussed in the case where long-range Coulomb coupling is active.
