p&Lambda invariant mass (top) and total energy (bottom) spectra classified by cos(p&Lambda).lt.-0.60(red) and gt.-0.60(green).
p&Lambda invariant mass, in coincidence with additional n(red)/&gamma(green)/&pi(magenta)/p(sky-blue). The original spectrum is shown by black, and coincidence spectra are scalled by factor 10.0 .
nucleon momentum, in coincidence with &Lambda N pair.
