Multineutron photodisintegration of the {sup 197}Au nucleus behind the giant dipole resonance
- Moscow State University, Institute of Nuclear Physics (Russian Federation)
An experiment in which the gold isotope {sup 197}Au was irradiated with a beam of bremsstrahlung photons having an endpoint energy of E{sub {gamma}}{sup m} = 67.7 MeV and originating from the RTM-70 racetrack microtron of the Institute of Nuclear Physics at Moscow State University was performed. The gammaray spectra of the residual beta activity of an irradiated sample were measured. Multinucleon photonuclear reactions on {sup 197}Au nuclei were observed in the experiment. Photonuclear reactions on a {sup 197}Au nucleus that involve the emission of up to seven neutrons were recorded for the first time. The experimental results in question suggest the important role of the quasideuteron photodisintegration mechanism in the energy region behind the giant dipole resonance.
