5. Commissioning of the two arm magnetic spectrometer and study of effective polarization phenomenon in nuclei.

     A new series of p,2p experiments was started in the year 1993. A (new) low momentum arm of the magnetic spectrometer was put into operation together with two proportional chamber polarimeters installed in each spectrometer arm. Two final protons were detected in coincidence at non-symmetric scattering angles 18-25deg. and 53.2deg. by the forward (high momentum) and the recoil (low momentum) spectrometer arm, respectively. Overall resolution on separation energy Es varied from 2 to 3MeV. The polarizations of both scattered protons were measured.
     Phenomenon of effective polarization of a nucleon in a nucleus was studied using this apparatus.
