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.
