Title: | Overall picture of the cascade gamma decay of neutron resonances within a modified practical model | Authors: | Sukhovoj A. Mitsyna L. Jovančević, Nikola |
Issue Date: | 1-May-2016 | Journal: | Physics of Atomic Nuclei | Abstract: | © 2016, Pleiades Publishing, Ltd. The intensities of two-step cascades in 43 nuclei of mass number in the range of 28 ≤ A ≤ 200 were approximated to a high degree of precision within a modified version of the practical cascade-gammadecay model introduced earlier. In this version, the rate of the decrease in the model-dependent density of vibrational levels has the same value for any Cooper pair undergoing breakdown. The most probable values of radiative strength functions both for E1 and for M1 transitions are determined by using one or two peaks against a smooth model dependence on the gamma-transition energy. The statement that the thresholds for the breaking of Cooper pairs are higher for spherical than for deformed nuclei is a basic result of the respective analysis. The parameters of the cascade-decay process are now determined to a precision that makes it possible to observe the systematic distinctions between them for nuclei characterized by different parities of neutrons and protons. | URI: | https://open.uns.ac.rs/handle/123456789/4718 | ISSN: | 10637788 | DOI: | 10.1134/S1063778816020174 |
