Abstract

An experiment for knockout reaction induced by 8He beam at 82.5MeV/nucleon on CH₂ and C targets was carried out. The ⁶He and ⁴He core fragments at forward angles and the recoiled protons at large angles were detected coincidently. From this exclusive measurement the valence nucleon knockout mechanism and the core knockout mechanism are separated, which can be applied to the exclusive spectroscopic study on the structure of exotic nuclei.
