Abstract
The traditional hard-disk Lorentz gas describes the chaotic motion of a cla ssical point particle through an array of impenetrable disks. Soft-disk mod ifications of the two-dimensional Lorentz gas, where the scattering particl e can move into the disk interiors, are considered here. Conditions on the soft-disk potentials and disk separations that guarantee chaotic motion are obtained.
