Strong spin-orbit coupling lifts the degeneracy of t_2g orbitals in 5d transition-metal systems, leaving a Kramers doublet and quartet with effective angular momentum of J_eff = 1/2 and 3/2, respectively. These spin-orbit entangled states can host exotic quantum phases such as topological Mott state, unconventional superconductivity, and quantum spin liquid. The lacunar spinel GaTa₄Se₈ was theoretically predicted to form the molecular J_eff = 3/2 ground state. Experimental verification of its existence is an important first step to exploring the consequences of the J_eff = 3/2 state. Here, we report direct experimental evidence of the J_eff = 3/2 state in GaTa₄Se₈ by means of excitation spectra of resonant inelastic x-rays scattering at the Ta L₃ and L₂ edges. In conclusion, we found that the excitations involving the J_eff = 1/2 molecular orbital were absent only at the Ta L₂ edge, manifesting the realization of the molecular J_eff = 3/2 ground state in GaTa₄Se₈.
