Study of the Identical Bands of Odd-A and Odd-Odd Nuclei in the A~190 Mass Region

  • the microscopic mechanism of the identical bands in odd-odd nucleus 194Tl and its neighbor odd-A nucleus 193Tl are investigated using the particle–number conserving (PNC) method with monopole and quadrupole pairing interaction. It is found that the blocking effect plays an important role in the variation in moments of inertia (J(1) and J(2)) with rotational frequency for the sd bands and identical bands. And the angular momentum alignment i(ω) of the six SD bands in 194Tl relative to the 193Tl(1) also is discussed.

Abstract: the microscopic mechanism of the identical bands in odd-odd nucleus 194Tl and its neighbor odd-A nucleus 193Tl are investigated using the particle–number conserving (PNC) method with monopole and quadrupole pairing interaction. It is found that the blocking effect plays an important role in the variation in moments of inertia (J(1) and J(2)) with rotational frequency for the sd bands and identical bands. And the angular momentum alignment i(ω) of the six SD bands in 194Tl relative to the 193Tl(1) also is discussed.
