The results of a search for the photoproduction of charmed baryons in the broad-band neutral beam at Fermi National Accelerator Laboratory are reported. The lowest lying charmed baryon (..lambda../sub c//sup +/) is observed through its decay to p-anti K/sup 0/. The cross section times branching ratio is measured to be sigma B = 3 nanobarns/nucleon. The total error on this measurement is estimated to be -20% to 40%. The mass of the ..lambda../sub c//sup +/ is found to be 2.284 +- 0.001 GeV/c/sup 2/, in good agreement with the Mark II result from SPEAR. Upper limits (90% confidence level) are set on sigma B for the modes ..lambda../sup 0/..pi.., ..lambda../sup 0/..pi pi pi..,pK..pi...
