Simultaneous analysis of elastic scattering and fusion in ⁶He + ⁶⁴Zn: A transition in direct reaction mechanisms, striking threshold anomalies, and halo effects

NUCLEAR REACTIONS ⁶⁴Zn(⁶He, ⁶He), E(cm)=9.0, 12.3, 13.6, 16.4 MeV; analyzed experimental data for differential σ(θ, E); deduced strengths for the polarization potentials, fitting parameters leading to dispersive potential. ⁶⁴Zn(⁶He, X), E(cm)=6-18 MeV; calculated total σ(E), fusion σ(E), α particle angular distributions, energy dependence of the real and imaginary strengths of the fusion polarization potential, reduced total reaction σ(E). Extended optical model. Comparison with experimental data.
