We present a study of Bs0 decays to the CP-odd final state J/ψ f₀(980) with J/ψ → µ⁺µ^- and f₀(980) → π⁺π^-. Using pp̄ collision data with an integrated luminosity of 3.8 fb^-1 collected by the CDF II detector at the Tevatron we measure a Bs0 lifetime of τ(B⁰_s → J/ψ f₀(980)) = 1.70_-0.11^+0.12(stat) ± 0.03(syst) ps. This is the first measurement of the Bs0} lifetime in a decay to a CP eigenstate and corresponds in the standard model to the lifetime of the heavy Bs0 eigenstate. We also measure the product of branching fractions of B⁰_s → J/ψ f₀(980) and f₀(980) → π⁺π^- relative to the product of branching fractions of B⁰_s → J/ψφ and φ→K⁺K^- to be R_{f_0/ψ} = 0.257 ± 0.020(stat) ± 0.014(syst), which is the most precise determination of this quantity to date.
