It is proved that the singular semilinear elliptic equation −Δu = p(x)g(u), 0 ≤ p(x),x ∈ Rn, 2 ≤ n, lims → 0+g(s) = +∞, andg ∈ C1((0, ∞), (0, ∞)) which is strictly decreasing in (0, ∞), has a unique positiveC2 + αloc(Rn) solution that decays to zero near ∞ provided ∫∞0 tϕ(t)dt < ∞, where ϕ(t) = @imax@i|x| = tg(x).
