Experimental study and theoretical consideration of the isomeric ratio in the photonuclear reaction 197Au(γ, n)196m,g Au in the giant dipole resonance region

We have carried out a study on the isomeric ratio in the ¹⁹⁷Au(γ, n)^196m,g Au photonuclear reaction in a giant dipole resonance region with bremsstrahlungs produced by electron accelerator Microtron MT-25 of the Flerov Laboratory of Nuclear Reactions, JINR. The isomeric ratio has been determined from a series of gamma spectra measured with a high-energy-resolution gamma spectrometric system consisting of an HPGe detector and a multichannel analyzer. The results have been discussed, compared with those of other authors, as well as considered by the statistical model supposed by Huizenga and Vandenbosch.
