Beta-decay and structure of odd nuclei, suppression of weak forces in nuclei
Results of calculations in the framework of the dynamic collective model of probabilities of beta-transitions for more than 20 nuclei with mass numbers from А = 31 to А = 231 with one universal renormalization of weak interaction constants are presented. The quasi-particle and many-phonon (up to 10...

| Summary: | Results of calculations in the framework of the dynamic collective model of probabilities of beta-transitions for more than 20 nuclei with mass numbers from А = 31 to А = 231 with one universal renormalization of weak interaction constants are presented. The quasi-particle and many-phonon (up to 10 phonons) states, as well as vacuum fluctuations of quasi-particles were taken into account. The calculated values lg ft show good agreement with the experimental data. In the aggregate the results of the calculations show that suppression of weak forces in nuclei does not depend on mass number and energy of states excited in beta-decay. |
