The search for possible mesolensing of cosmic gamma-ray bursts. Double and triple bursts in BATSE catalogue

The work is devoted to the search for possible effect of gravitational lensing on the objects like globular stellar clusters (mesolensing) on the lightcurves and spectra of large number of gamma-ray bursts from BATSE catalogue. The general properties and different types of such event were considered. As the result 11 possibly mesolensed gamma-ray bursts were found. The properties of possible mesolensed are investigated.
