Destruction of dirty ice mantles by sputteringDirty ice mantles are destroyed efficiently by sputtering of He atoms when clouds encounter shock velocities greater than 13-15 km/sec. Destruction due to grain-grain collisions is found to be about .001 times less efficient. Sputtering in the hot intercloud medium should make intercloud grains smaller than cloud grains.
