Mass distribution of fission products has been determined in 
reaction at 
MeV using 
particles from the cyclotron at the Variable Energy Cyclotron Centre (VECC), Kolkata. Yields of 64 fission products having half-lives in the range of about 
min to several days have been measured using gamma ray spectrometry. The mass distribution shows a clear triple humped structure indicating the contribution from both asymmetric and symmetric modes of fission. The experimental mass distribution was well reproduced by the calculation from the GEF code, which takes into account the multi-chance fission.
