Production of the charmed baryon {Lambda}{sub c} has been observed in n-nucleus collisions at the Proton East area of FNAL. A 5{sigma} peak was seen in the decay mode {Lambda}{sub c}{sup +} {yields} pK{sup {minus}}{pi}{sup +} (and charge congugate). The lifetime was determined to be consistent with the current world average of 0.23 ps, and the cross section of {Lambda}{sub c}{sup +} at {radical}s = 33 GeV was measured to be {sigma} {center dot} BR = 2.1 {plus minus} 1.1 ({plus minus}.74){mu}b/nucleon for 0.028 < x{sub f} < 0.226. The fraction of {Lambda}{sub c}{sup +}/({Lambda}{sub c}{sup +} + {Lambda}{sub c}{sup {minus}}) was estimated to be 78% {plus minus} 18%.
