Abstract

Yields of projectile fragments have been measured at 0° for the reaction of 205-MeV/nucleon ${}^{40}{Ar}$ ions on an 860-mg- ${cm}^{- 2}$ carbon target. Mass resolution was achieved using a combination of magnetic analysis and energy-loss measurements. The isotopes ${}^{28}{Ne}$ and ${}^{35}{Al}$ have been observed for the first time.
