Abstract

That part of the dynamic polarization potential due to the coupling to rotational states is represented in three ways: as a local, l-independent potential, S-matrix equivalent to the formal DPP; as an angle dependent ‘ψ-potential’; and as an l-dependent potential. Apart from requiring a selection of particular states, the general approach to the DPP of which we compare three variants, does not require certain commonly imposed approximations. A comparison of the representations of the DPP leads to insight concerning the applicability of simple potential models, general properties of the DPP, estimates of the effects of approximations and indications of the sensitivity of DPP estimations upon the coupling parameters. In particular we show that different extreme sets of parameters, for which (in the case studied) there is insufficient data to categorically eliminate either extreme, lead to DPP's of opposite signs. The emphasis in this paper is on comparing methodologies rather than final conclusions concerning the DPP.

Heavy-ion scattering and reactions near the Coulomb barrier and "threshold anomalies"
1991, Physics Reports
The couplings between the various reaction channels available for the collision of two heavy ions become especially important at energies near the top of their mutual Coulomb barrier. In particular, they result in a “threshold anomaly” in the dependence on energy of the optical model potential that describes their elastic scattering and a strong enhancement of their fusion cross sections in this energy region. The evidence for these “anomalies” is reviewed and their theoretical explanation is discussed. A dispersion relation between the real and imaginary parts of the optical model potential is described and its use is illustrated. Finally, an extension of the one-channel optical model that allows for simultaneous analysis of fusion and elastic scattering is presented and its applications are considered.
The O + Pb interaction near the coulomb barrier
1990, Nuclear Physics, Section A
We present the local and l-rmindependent potentials which are equivalent, in the sense that they yield the same S_l, to the implicit polarization potentials generated by channel coupling, and which have been found by Thompson et al. to explain the threshold anomaly for the case of ¹⁶O on ²⁰⁸Pb. Potentials which fit S_l for all partial waves are irreducibly wavy in r, an effect which appears to be a consequence of the l-dependence of the dynamic polarization potential. To establish these potentials, the “IP” inversion procedure was further developed. Some of our results are unexpected, including a very low degree of energy dependence in the real potential in the energy range between 80 and 102 MeV. The most general aspects of what we find here appear to be consistent with behaviour common to all nucleus-nucleus potentials, including those involving nucleons as projectiles.
On the coupled-channel calculation of the optical potential with full inclusion of coupling effects
1990, Physics Letters B
We develop a method for a coupled-channel calculation of the optical potential in which the multichannel Green's function is evaluated exactly. The quantum-mechanical coupled-channel problem is solved by expanding the multichannel interactions in terms of coupled sturmians. Closed-and open-channel effects are straightforwardly included by the use of energy-dependent basis functions. An application in the framework of a schematic multichannel model is developed.
