Approximation Analysis

Zero-range distorted-wave Born approximation calculations are used to investigate the systematics of two-nucleon transfer reactions. The shapes of the calculated 40Ca(t,p)42Ca(gs) and 208Pb(p,t)206Pb(gs) cross sections are relatively insensitive to details of the core plus two-neutron form factor, if the form factor tails have similar shapes. Studies of heavy targets such as 206Pb suggest a surface reaction mechanism, but lighter targets (16O and 40Ca) indicate that spatial regions beyond the target surface provide the dominant contribution to the (p,t) cross section.

The reactions 68Zn(d,6Li)64Ni(0+,g.s.) and 68Zn(d,6Li)64Ni(2+, 1.34 MeV) are investigated using the zero-range distorted wave Born approximation (ZRDWBA). ZRDWBA calculations indicate that the optical parameter set of Fulbright et al. provides a good representation of the transfer data, and that adjustments to Coulomb radii or form factor quantum numbers are not necessary. Relative strengths for the 0+ and 2+ levels are found to vary by a factor of two when reasonable changes to form factor geometries are made.

Angular distributions of the differential cross sections and analysing powers were measured at an energy of 4.6 MeV. The results are compared with the distorted wave Born approximation predictions for two-nucleon transfer and for a deuteron-cluster transfer. The agreement is qualitative at best, and a discussion of alternatives to improve it is presented.
