Inclusive breakup cross sections in reactions induced by the nuclides ⁶He and ^{6, 7}Li in the two-body cluster model

NUCLEAR REACTIONS ⁶⁴Zn, ²⁰⁹Bi(⁶He, α), E=9-25 MeV; ⁶⁴Zn(⁶He, α), E=9.8, 13.5, 14.85, 17.9 MeV; ¹²⁰Sn(⁶He, α), E=17.4, 18.05, 19.8, 20.5, 22.2 MeV; ²⁰⁸Pb(⁶Li, α), (⁶Li, d), E=19-40 MeV; ⁹⁰Zr(⁶Li, α), E=14-31, 19, 21, 25, 30 MeV; ⁵⁸Ni(⁶Li, α), E=14, 16, 18, 20 MeV; ¹¹⁸Sn(⁶Li, α), E=18, 19, 21, 24 MeV; ⁵⁶Fe(⁷Li, α), E=68 MeV; ⁵⁸Ni(⁷Li, α), E=14.22, 16.25, 18.28, 20.31 MeV; calculated inclusive σ(E) for α and deuteron emission, α angular distributions, and spectra; deduce zero-range overall large contribution from inclusive breakup emission of α particles. Zero-range post-form Ichimura, Austern, and Vincent (IAV)-distorted-wave Born approximation (DWBA) formalism for elastic and nonelastic breakup cross sections, with Wood-Saxon parametrization of Sao Paulo optical potential with a modified diffuseness, and with projectiles treated as two-body clusters, ⁶He as α+dineutron, ⁶Li as α+d and ⁷Li as α+triton. Comparison with experimental data.

Emergent universality in the two-neutron halo structure of ²²C

NUCLEAR STRUCTURE ²²C; calculated S(2n), ρ² and r_n, halo-neutron density, effective adiabatic potential, contour plot of the density, and two-neutron halo structure using three-body (neutron-neutron-core) model with finite-range potentials, from hyperspherical adiabatic expansion method, and with the renormalized zero-range model.
