PROPERTIES OF POSITIVE PARITY STATES IN 230-232th ISOTOPES

Аннотация

Non–adiabatic effects manifested in the energies and electrical characteristics of 230,232 positive parity states of Th nucleus been studied within the framework of a phenomenological model, taking into account the Coriolis mixing of low–lying rotational state + + + bands. The energy and structure of low–laying state of 0 2 (b-), 2 n (g-) and 1 n bands which is constructed on intrinsic excitation are calculated. And also the reduced probabilities of E2- transitions from the 0 + and 2 + bands tothe ground 0 +( gr-) stateband have been calculated. 2 n 1 The non–adiabatic effect which is manifesting in electromagnetic transitions and significantly effects inthewave function ofthe states isshown.
