We study spatially homogeneous inelastic gases using the Boltzmann equation. We consider uniform collision rates and obtain analytical results valid for arbitrary spatial dimension d and arbitrary dissipation coefficient . In the unforced case, we find that the velocity distribution decays algebraically, P(v,t)~v-σ, for sufficiently large velocities. The exponent σ(d,) exhibits nontrivial dependence on the spatial dimension and the dissipation coefficient.
