Energy spectra and charge distributions have been measured for multifragment disintegrations in Kr + Au collisions at E/A = 35, 55, 70, 100, 200, and 400 MeV. Mean transverse energies determined for fragments significantly exceed those predicted for molecular dynamical and dynamical - statistical hybrid calculations. The measured fragment charge distributions are consistent with a {open_quotes}power-law{close_quotes} falloff, that is more gradual than that consistent with recent {open_quotes}critical exponent{close_quotes} determinations. Comparison with statistical calculations reveal that such fragment distributions are strongly altered by the secondary decay of excited fragments.
