Reliable identification of the above mentioned resonances requires to use 4pi and high precision measurements of the sought objects. The 2m propane bubble chambers(PBC) with precision film methods is unique multi-propose and higher-informative 4pi detector for study of exotic multi-strange events with V0 particles, light hyper-nucleus,V0-V0 interactions and other correlations. The full experimental information of more than 700 000 stereo photographs or million p+propane inelastic ineractions at 10 GeV/c have been used to collect of events with V0 strange particles.

Reliable identification of the above mentioned resonances requires to use 4pi and high precision measurements of the sought objects. The 2m propane bubble chambers(PBC) with precision film methods is unique multi-propose and higher-informative 4pi detector for study of exotic multi-strange events with V0 particles, light hyper-nucleus,V0-V0 interactions and other correlations. The full experimental information of more than 700 000 stereo photographs or million p+propane inelastic ineractions at 10 GeV/c have been used to collect of events with V0 strange particles. The fit of the GRIND-based program GEOFIT is used to measure the kinematic parameters of the tracks: p(momentum), alpha(depth angle) and beta(azimuth angle). The momentum resolution is to 2.1% for stopped particles and 9.8% for nonstopped particles. The mean values for errors of the depth and azimuth angles are equal to 0.7 and 0.3 degree, respectively. The observed well known Sigma( +)(1385) and K( +)(890)resonances are a good test for this method. A survey of new experiments with much improved statistics compared to those early PBC data would hopefully answer the question whethersuch "exotic" exist.
