Study of polarization in quasi‐elastic break‐up reaction 6Li(p,2p)5He in complete kinematics at 1 GeV

The polarization of recoil protons from the reaction 6Li(p,2p)5He at 1 GeV of incident proton beam energy was measured with a new two‐arm magnetic spectrometer with a carbon polarimeter. The effective polarization of the P‐shell protons of 6Li nucleus was calculated and found to be in a qualitative agreement with the predictions of the cluster model rather than with those of the shell model.
