Abstract
A search for the decay 0X, where X is any long-lived weakly interacting neutral vector particle with mass smaller than the neutral pion pass, was performed using neutral pions tagged by K+0. A 90%-C.L. upper limit for the branching ratio of the two-body decay B0X)<5×10-4 is set. Limits are also set for three-body decays 0XX.
