Characteristics of superconductivity induced by pressure P in EuMo/sub 6/S/sub 8/ have been investigated by dc magnetization and heat capacity measurements under nearly hydrostatic pressure. No Meissner effect was detected at the superconducting transition, in agreement with previous results, but a discontinuity in the heat capacity data demonstrates the bulk nature of the superconducting state for P> or approx. = 13 kbar. An analysis of the heat capacity data yields a value for this discontinuity comparable to that expected from the BCS theory. In addition, heat capacity measurements for P = 11 kbar reveal a feature arising from the structural transition responsible for the absence of superconductivity when P < 13 kbar in EuMo/sub 6/S/sub 8/.
