This paper reports the investigations carried out on isotopic enrichment in boron oxide plasma produced by a Nd : glass laser giving 20 MW in 30 nsec (FWHM). Energy distributions of various ions in the plasma expanding in vacuum were obtained with an electrostatic ion analyzer. Energies corresponding to peaks of distribution for /sub 10/B/sup +/ and /sub 11/B/sup +/ were found to be different by the ratio of their masses, consistent with hydrodynamic expansion of plasma. An anomalously high ratio of /sub 10/B/sup +/ to /sub 11/B/sup +/ ions as compared to their natural abundance was observed.
