Abstract

The ⁶Li(p, pα)d, ⁶Li(p, pα)np and ⁶Li(p, pp)⁵He (g.s.) reactions were measured at 11 and 12 MeV bombarding energy, θ₁ = 135° and θ₂ = 30°. In the coincidence spectra, final state interactions (FSI) corresponding to the J^π = 2⁺ doublet in ⁶Li were clearly seen and their widths and energy positions determined. In addition, the p-α spectrum gives evidence for a level in ⁶Li at 5.7 MeV excitation with a width of approximately 1 MeV. No indication for decay of the ⁶Li(5.37 MeV, 2⁺, T = 1) state in the d-α channel was found. By comparing the corresponding yields in the isospin allowed and forbidden channels, an upper limit of α² ≦ 8 × 10⁻³ was deduced for a possible T = 0 admixture in the T = 1 state at 5.37 MeV.

Isospin mixing and energy distributions in three-body decay
2007, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
The structure of the second $2^{+}$ resonance in ⁶Li is investigated with special emphasis on its isospin 0 components. The wave functions are computed in a three-body model ( $α + n + p$ ) using the hyperspherical adiabatic expansion method combined with complex scaling. In the decay into three free particles the symmetry conserving short-range interaction dominates at short distance whereas the symmetry breaking Coulomb interaction dominates at intermediate and large distances resulting in substantial isospin mixing. We predict the mixing and the energy distributions of the fragments after decay. Computations are consistent with available experiments. We conjecture that nuclear three-body decays frequently produce such large isospin mixing at large distance where the energy distributions are determined.
Isospin-forbidden d* production in the 4He(d,pαn reaction with tensor-polarized beam
1982, Nuclear Physics, Section A
The $^{4} He (d, p α) n$ reaction has been studied in a kinematically complete experiment using a tensor-polarized deuteron beam to investigate the isospin-forbidden pn final-state interaction. A clear dependence of the cross section near E_pn = 0 on the spin state of the incoming deuterons has been found as expected if the bumps observed by several authors at small pn relative energies are indeed due to the isospin-forbidden proton-neutron FSI in the ¹S₀, T = 1 state.
