    "abstract": "We show that when the Hornberger--Sipe calculation of collisional decoherence\nis carried out with the squared delta function a delta of energy instead of a\ndelta of the absolute value of momentum, following a method introduced by\nDi\\\u0027osi, the corrected formula for the decoherence rate is simply obtained. The\nresults of Hornberger and Sipe and of Di\\\u0027osi are shown to be in agreement. As\nan independent cross-check, we calculate the mean squared coordinate diffusion\nof a hard sphere implied by the corrected decoherence master equation, and show\nthat it agrees precisely with the same quantity as calculated by a classical\nBrownian motion analysis.",
