Received 10 September 1997; published in the issue dated 1 April 1998
Using data recorded by the CLEO-II detector at CESR, we report new measurements of the branching fractions for the decays of the charmed baryon Λc+ into pK-π+π0, pK0, pK0π+π-, and pK0π0, all measured relative to pK-π+. The relative branching fractions are 0.67±0.04±0.11,0.46±0.02±0.04,0.52±0.04±0.05, and 0.66±0.05±0.07, respectively.
