Abstract

One-proton removal reactions of 936 MeV/u ⁸B have been studied with carbon and lead as breakup targets. Using the FRS at GSI, the longitudinal momentum distributions of the ⁷Be fragments and the one-proton removal cross section of 8B were measured. The relative contributions of the breakup channels leading to ⁷Be in its ground state and excited state at 429 keV (⁷Be*) have been determined from measurements of rays in coincidence with the fragments from the one-proton removal reaction. The experimental breakup data are discussed in the context of a theoretical (+3He+p) three-body model. The combined data from the two targets allow a determination of the weight of the 7Be* component in the ⁸B ground state wave function as (13.3±2.2%)
