A detailed low-energy level scheme of the odd-odd n-rich nucleus 184 73Ta111 is constructed using the well tested Two-Quasiparticle Rotor Model (TQRM) for calculating the bandhead energies of physically admissible 2qp configurations with the inclusion of residual n-p interaction contribution. The presently available data on this level scheme from 184Hf decay are shown to be in agreement with these calculations. Our analysis concludes that 184Hf ( keV) decay admits of 7 additional (to the 3 presently reported) -branches to 184Ta with or 1 and 8 more physically admissible weak ( -branches populating levels in 184Ta. Further, a close examination of our level scheme clearly indicates the existence of a low-lying ( keV) high-spin () long-lived isomer in this nucleus.
