Production of the charmed strange baryon Xi c+ by neutrons.
We report on the observation of a narrow resonance at a mass of 2459 MeV/c/sup 2/ in the final states ..lambda..K/sup -/..pi../sup +/..pi../sup +/ and ..sigma../sup 0/K/sup -/..pi../sup +/..pi../sup +/. The mass, width, lifetime, and decay modes support the interpretation of a hadronically produced charmed strange baryon, the ..gamma../sub c//sup +/. We present our measurements of the lifetime, cross section, and relative branching fractions, and the A, x/sub f/, and p/sub t/ dependence of the state.
