Measurement of charges ( 1 £ Z £ 3) of the projectile fragments produced in silicon-emulsion interaction at 14.5 AGeV was carried out with the help of lacunarity (L) method, using nuclear emulsion track detector. No fractionally-charged projectile fragment was found in this investigation. Only integrally-charged projectile fragments with Z=1,2 and 3 were detected.
