The Independent Quark Model, formulated for a three-body system within a relativistic framework, is applied to singly heavy baryons \( Ωc0 \) and \( Ωb- \) to investigate their spectroscopic properties. A Martin-like potential with an equal mixture of scalar and vector components is employed, with potential parameters fitted using ground-state experimental data. The resulting mass spectra include both radial and orbital excitations. The spin-parity for the recently observed states \( Ωc0(3000) \), \( Ωc0(3050) \), \( Ωc0(3067) \), \( Ωc0(3120) \), and \( Ωc0(3185) \) as well as possible spin assignments for the four newly observed excited states of \( Ωb- \) (\(Ωb-(6316)\), \(Ωb-(6330)\), \(Ωb-(6340)\), and \(Ωb-(6350)\)) are proposed. The magnetic moments of the ground and first excited states are also calculated, along with radiative decay widths and transition magnetic moments. The non-leptonic weak decays of \( Ωc0 \) are analyzed, with decay widths and branching ratios computed and compared with experimental data to validate the predictive power of the model. The branching ratios for the non-leptonic decays of Ωb- are also predicted for future observations.
