Study of excited states and observation of collective level structures in the odd-odd nucleus ¹⁹⁴Bi

NUCLEAR REACTIONS ¹⁵⁹Tb(⁴⁰Ar, 5n)¹⁹⁴Bi, E=182, 185, 190 MeV; measured Eγ, Iγ, γγ-coin from α-decay of the ¹⁹⁴Bi α-radioactive reaction products decay using the recoil gating technique; deduced rotational bands levels energy, I_γ, J^π for initial and final states, multipolarity, angular distribution ratios, linear polarization asymmetry factors, ¹⁹⁴Bi level scheme, excitation energy minus rigid-rotor reference term vs spin, aligned angular for the favoured and unfavoured signatures of positive and negative parity in several bds.
