Description

Isovector M1 transitions between low-lying T = 1 and T = 0 states in odd-odd N = Z nuclei are discussed. The data on low-spin states in the odd-odd nuclei 46V and 50Mn investigated with the 46Ti(p, nγ)46V and 50Cr(p, nγ)50Mn fusion evaporation reactions at the FN-TANDEM accelerator are reported. Simple explanation of the enhancement of the M1 transitions is shown to be due to the coupling of the two-particle configurations to the rotating core

Abstract (Russian)

Обсуждаются изовекторные М1 переходы между низколежащими Т = 1 и Т = 0 состояниями в нечетно-нечетных N = Z ядрах. Представлены данные по низко-спиновым состояниям в нечетно-нечетных 46V и 50Mn ядрах, исследованных вместе с 46Ti(p, nγ)46V и 50Cr(p, nγ)50Mn реакциях слияния на ускорителе FN-TANDEM. Простое объяснение увеличения М1 переходов дано в терминах квази-дейтронных конфигураций. Показано, что фрагментация сильных М1-переходов идет благодаря взаимодействию двухчастичных конфигураций во вращающемся ядре
