Direct and compound-nucleus reaction mechanisms in the ⁷Be + ⁵⁸Ni system at near-barrier energies

NUCLEAR REACTIONS ⁵⁸Ni(⁷Be, ⁷Be), (⁷Be, ³He), (⁷Be, α), E=22 MeV, [⁷Be beam from ¹H(⁷Li, ⁷Be), E=34.2 MeV using EXOTIC facility at LNL-Legnaro]; measured reaction products, angular distributions of ³He and ⁴He, quasielastic σ(θ), breakup σ(θ) using ΔE-E telescopes of the DINEX setup, part of the GLORIA detector array; deduced correlation plot of energy versus detection angle θ_lab, quasielastic σ(θ), reconstructed Q value spectrum. ⁵⁸Ni(⁷Be, ⁸Be), (⁷Be, ⁶Be), E=22 MeV; deduced σ(θ) for neutron pickup and stripping processes. Monte Carlo simulations for the elastic scattering process and inelastic excitation. Optical-model, continuum-discretized-coupled-channel (CDCC) calculations using the code FRESCO, and DWBA calculations. Discussed role of breakup, ³He-stripping, 1n-stripping, and 1n-pickup processes.
