Study of high energy gamma-rays in heavy ion reactions
Description
The gamma-spectra up to gamma-ray energy of 20 MeV in coincidence with KX-rays and fission fragments were measured. The reactions induced by 15N, 22Ne, 40Ar ions with E/A=5.5-10 MeV/nucleon leading to the formation of the Yb or Bi compound nuclei were studied. The 130Te, 150Te, 150Nd, 153Eu, 159Tb, 181Ta, and 192Os targets were used. The gamma-rays were registered by a NaJ(Tl) scintillation detector with phi 150x100 mm dimensions. The effective temperature of the gamma-ray spectrum has been determined in the 4 MeV < E < 12 MeV range and its dependence on the projectile mass has been established. Broad bumps have been oserved in the E > 12 MeV energy region. The possible correspondene between these bumps and the gamma-decay of giant dipole resonance built on highly excited states of compound nuclei and projectiles is discussed
