    "abstract": "We consider a soluble model of multifragmentation which is similar in spirit\nto many models which have been used to fit intermediate energy heavy ion\ncollision data. In this model $c_v$ is always positive but for finite nuclei\n$c_p$ can be negative for some temperatures and pressures. Furthermore,\nnegative values of $c_p$ can be obtained in canonical treatment. One does not\nneed to use the microcanonical ensemble. Negative values for $c_p$ can persist\nfor systems as large as 200 paticles but this depends upon parameters used in\nthe model calculation. As expected, negative specific heats are absent in the\nthermodynamic limit.",
