摘要：

Evidence of massive neutrinos was sought in the pi(+) --> mu(+)x decay spectrum in the mass region M(x) = 30-33.91 MeV/c(2). Upper limits on the branching ratio R(mu x) less than or equal to (4 - 6) x 10(-5) (90 % C.L.) were set for this region, which correspond to the neutrino mixing parameter / U-mu x /(2) < 10(-3)-10(-4).
