Abstract

Knockout of α clusters from light and medium weight nuclei by 600 MeV protons has been investigated. The outgoing protons and α particles were detected in coincidence; their momenta were measured with two large magnetic spectrometers with proportional wire chambers. Experimental methods which were used to work with a high beam rate and an efficient proton rejection in the α arm are described. Separation energy spectra are given for Li6, Li7, C12, Mg24, Al27, and Ca40 nuclei. A peak is observed at an excitation energy equal to zero, except for the Al27 target.

NUCLEAR REACTIONS Li6, Li7, C12, Mg24, Al27, Ca40(p, pα), E0=600 MeV; experimental methods; separation energy spectra.
