QUADRUPOLE GAMMA-SUPERRADIANCE

The prevalence of multipole transitions over dipole ones is a characte ristic feature of nuclear radiation processes. We consider here quadru pole gamma superradiance. The ways of macroscopic quadrupole formation are discussed. The superradiance kinetics is analyzed by means of the method of the nonequilibrium statistical operator. The superradiance intensity is shown to be proportional to the fourth degree of the numb er of particles, although the proportionality coefficient is rather sm all.
