Study of intermediate excited states above the I=10⁺ isomer in the ¹³⁶Ba nucleus

Nuclei having the proton number (Z) in the range of 50-64 and neutron number (N) in the vicinity of N=82 shell closure exhibit an interplay of single-particle and low quadrupole collectivity. Fermi surface of the these nuclei occupies the proton d_5/2, g_7/2 and h_11/2 orbitals and neutron g_7/2, d_/2, s_1/2 and h_11/2 orbitals. Mostly, the multi-nucleon transfer reactions were used to excite the state above the I^π = 10⁺ in even-even nuclei and interpreted systematic shell-model calculations. The spin and parity of these states was assigned from the angular correlation studies. In present work, we report on the extension of intermediate states above I^π = 10⁺ and spin and parity measurement based on DCO and polarization asymmetry measurement. The shell-model calculations have been performed for both the positive and negative parities for the same observed state to understand the experimental structure
