On some questions of the population of isomeric states

The connection between the process of the population of isomeric states and some questions of the investigation of photo- and electronuclear reactions is discussed. On the example of the (n,γ) reaction on thermal neutrons and (γ,γ') reaction a model for the calculation of γ cascaded is demonstrated. A good agreement between the calculation results and experimental data has been achieved. A relative contribution of different multiplicities into the process of the population of isomeric states excited in the photoabsorption reaction and γ cascade is investigated. An earlier supposition on the possibility to use the reactions with the population of high spin isomeric states to extract E2-photoabsorption has been confirmed. 28 refs.; 4 figs.; 2 tabs
