An analysis is presented of events with a single jet and significant missing transverse energy selected from 4.7 pb[sup [minus]1] of p[bar p] data at [radical]s = 1800 GeV. The goal is to identify events of the type p[bar p] [yields] Z[sup 0] + jet; Z[sup 0] [yields] [nu][bar [nu]]. Event selection backgrounds are discussed. The number of observed monojet events is compared to the number of observed Z[sup 0] [yields] e[sup +]e[sup [minus]] events in which the Z[sup 0] is accompanied by a jet. We measure the number of light neutrino species to be N[sub v] = 2.2 [plus minus] 1.5 and we place an upper limit on the cross section for new physics of 8.3 pb (95% C.L.)
