Abstract
A measurement of the spin of the hyperon produced through the exclusive process is presented using a total integrated luminosity of recorded with the BABAR detector at the asymmetric-energy factory at SLAC. Under the assumption that the has spin , the angular distribution of the from decay is inconsistent with all half-integer spin values other than . Lower statistics data for the process from a sample are also found to be consistent with spin . If the spin were , an spin of could not be excluded.
