Dynamical multicluster model for electroweak and charge-exchange reactions

The hyperspherical harmonics method is used to solve the α+N+N three-body problem. The resulting wave functions and corresponding densities are, with satisfactory result, tested against a variety of weak and electromagnetic data as well as nucleon-induced quasielastic reactions (p,p’), (n,p), and (p,n) on ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ as target. A procedure is outlined which generates reliable transition densities for the (projectile, ejectile) part of ${}_{}{}^6{}_{}{}^{}\mathrm{induced}$ inelastic and charge-exchange reactions A${(}^6$Li,b)B, b${=}^6$Li*,${\mathrm{}}^6$He, and ${}_{}{}^6{}_{}{}^{}\mathrm{Be}$.
