The variety of isotopes in cosmic rays allows us to study different aspects of the processes that cosmic rays undergo between the time they are produced and the time of their arrival in the heliosphere. In this paper, we present measurements of the isotopic ratios 2 H/ 4 He, 3 He/ 4 He, 6 Li/ 7 Li, 7 Be/( 9 Be+ 10 Be), and 10 B/ 11 B in the range 0.2–1.4 GeV of kinetic energy per nucleon. The measurements are based on the data collected by the Alpha Magnetic Spectrometer, AMS-01, during the STS-91 flight in 1998 June.
