The decay of 1.83 GeV/c K/sup +/ mesons in flight was studied using a magnetic spectrometer with multi-wire proportional chambers for the charged particles and an array of lead glass to detect ..gamma..-rays from ..pi../sup 0/ decay. For the decay mode K/sup +/ yields ..pi../sup 0/..mu../sup +/nu/sub ..mu../ the muons were stopped after the spectrometer in a polarimeter, an array of carbon blocks and scintillators in a 40 g magnetic field. Four scintillators surrounded each carbon clock. The pattern of polarimeter counters in coincidence with the entering muon, and the pattern in coincidence with the decay positron were recorded, as well as the time delay between the ..mu../sup +/ and the e/sup +/. For events with two ..gamma..-rays striking the lead glass, the positions and energies of the ..gamma..-rays were also recorded. Each K..mu../sup 3/ decay with two detected ..gamma..-rays was a 2-C fit, with an additional constraint of range-momentum consistency for the muon. Polarization analysis on a final sample of 24,669 events gave a value Xi(q/sup 2/)/sub avg./ = -.25 +- .25. The experiment also gave values for Xi(q/sup 2/) in each of four q/sup 2/ bins.
