Abstract
A study of (p) over bar-annihilation in liquid deuterium into pi(-)pi( 0) pi(0) and a spectator-proton is presented. A cut on the proton-mome ntum of less than or equal to 100 MeV/c ensures that annihilation take s place on a quasi-free neutron. A partial wave analysis shows contrib utions from three vector mesons, with masses and widths of (763.7 +/- 3.2; 152.8 +/- 4.3), (1411 +/- 14; 343 +/- 20); (1780(-29)(+37); 275 /- 45) meV/c(2), respectively.
