[en] Angular distributions for the reactions ²⁶Mg(⁶Li, ⁷Besub(0.0))²⁵Na and ²⁶Mg(⁶Li, ⁷Besub(0.43))²⁵Na have been measured at E6sub(Li)=36 MeV. Elastic and inelastic scattering data for ⁶Li + ²⁶Mg have also been collected. The inelastic scattering has been analysed using a zero-range DWBA calculation and a value of 0.26 +- 0.02 has been extracted for the β₂ deformation parameter of the 2⁺(1.81 MeV) state in ²⁶Mg. An exact finite-range DWBA analysis of the single-proton pick-up reaction has been performed and the overall normalisation of the theoretical cross section was found to depend critically on the optical-model potentials used. A value for C²S for ²⁶Mg(0.0 MeV)→²⁵Na(0.0 MeV) + p of 3.0 +- 0.3 has been obtained using shallow heavy-ion radius potentials. This value is in good agreement with those deduced from light-ion work and with theoretical values. (author)
