Investigating neutron transfer in the ⁶Li + ¹²⁴Sn system

NUCLEAR REACTIONS ¹²⁴Sn(⁶Li, ⁶Li), E=19, 22.8, 24, 27, 30 MeV; calculated elastic σ(θ). ¹²⁴Sn(⁶Li, X)¹²⁵Sn/¹²³Sn, E=17-36 MeV; calculated σ(E) of 1n stripping and 1n pickup reactions. Four kinds of calculations have been performed - (i) coupled reaction channel (CRC) using phenomenological global optical model potentials, (ii) CRC using normalized microscopic Sao Paulo potentials, (iii) continuum discretized coupled-channel (CDCC) and (iv) combined CDCC+CRC. Systematics of 1n stripping and 1n pickup σ with ⁶Li projectile on various targets (²⁷Al, ⁹⁶Zr, ¹²⁴Sn, ¹⁵⁹Tb, ¹⁹⁷Au, ¹⁹⁸Pt). Comparison to experimental data on measured complete fusion, incomplete fusion, total fusion and neutron transfer cross sections.

Investigation of neutron transfer in ⁷Li + ¹²⁴Sn system

NUCLEAR REACTIONS ¹²⁰Sn(⁷Li, X), E=20, 22, 24, 26, 28 MeV; ¹²⁴Sn(⁷Li, X), E=18-36 MeV; ⁶⁵Cu, ⁹³Nb, ¹⁹⁷Au, ¹⁹⁸Pt, ²⁰⁹Bi(⁷Li, X); analyzed previous experimental σ(E, θ) data for ¹²⁰Sn+⁷Li reaction, and Σ(E) data for ¹²⁴Sn+⁷Li, one neutron stripping, two neutron stripping, and combined one neutron and one proton pickup cross sections using continuum discretized coupled channels (CDCC) and CDCC+coupled reaction channel (CRC) calculations using energy levels and spectroscopic factors for ^123,125Sn residual nuclei, global phenomenological optical model, and Sao Paulo potential; deduced significant contribution from 1-n stripping, and that proton stripping, noncapture breakup and target inelastic states may be necessary for a complete description of the reaction cross section.
