Dynamical multicluster model for electroweak and charge-exchange reactions.

The hyperspherical harmonics method is used to solve the {alpha}+{ital N}+{ital 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 ({ital p},{ital p}{prime}), ({ital n},{ital p}), and ({ital p},{ital n}) on {sup 6}Li as target. A procedure is outlined which generates reliable transition densities for the (projectile, ejectile) part of {sup 6}Li-induced inelastic and charge-exchange reactions {ital A}({sup 6}Li,{ital b}){ital B}, {ital b}={sup 6}Li*, {sup 6}He, and {sup 6}Be.
