Nuclear structure of the odd 177-183 Ta isotopes

الملخص EN

The energy of the positive excited states and electromagnetic transition probabilities in neutron-rich 177-183Ta isotopes have been calculated using interacting boson fermion model (IBFM-2).

The wave functions for all states have been investigated.

In present model space the fermions are allowed to excite to the 1g7/2 , 2d5/2 , 2d3/2, 3s1/2, and 1h11/2 single-particle orbitals.

It is found that these isotopes can be described by a schematic Hamiltonian of SU(3) limit.

The electromagnetic transition probabilities are analyzed which reveal the detailed nature of energy level.

The results obtained are in good agreement with available experimental data.
