Abstract: | It is inferred from the analysis of the experimental data that the reduced probabilities of isovector l-forbidden M1 transitions achieve maximum values in nuclei with a magic core. The minimum values are related to γ transitions in nuclei
belonging to the region of stable deformation with A ≈ 25. Isovector l-forbidden M1 transitions in mirror nuclei are explored. The ratio of the reduced probabilities for proton and neutron transitions shows
the maximum deviation from the theoretical evaluations for the pair of nuclei 41Ca-41Sc consisting of the even-even magic core 40Ca and one nucleon outside the closed 1d2s shell. |
