Abstract Power-law spectra f(E)∝E −2.7 of < 40 keV suprathermal ions within ∼107 km of propagating interplanetary shocks are explained by diffusive scattering near a plane shock. The theory fits the 25 November 1977 event with a mean free path perpendicular to the shock with is 0.01 AU in front of the shock and less than .0003 AU behind it, for 1 keV ions. The theory predicts a steepening spectrum at higher energies, of the form depends on the plasma velocity jump ΔV and the plasma speed VW and mean free path λ in front of the shock
