Abstract : A beam of ions, monochromatic in composition and energy, was passed through a gas and analyzed in a magnetic field. Beams were studied which consisted primarily, of the atomic ions: single-charged (He(+), N(+), Ne(+), K(+), Ar(+), Ca(+), J(+), Ba(+), Beams were studied which consisted primarily, of the atomic ions: single-charged (He(+), N(+), Ne(+), K(+), Ar(+), Ca(+), J(+), Ba(+), Pb(+), Bi(+)), double-charged (N(++), Ar(++), Ba(++)), triple-charged (Ar(+++)) and single-charged molecular ions (H(+)2, H(+)3, N(+)2). It became clear that such inelastic processes, linked to changes in the e/m of the ions in the beam, occur in single instances of a collision between an ion and a helium, neon. argon or krypton atom, or a hydrogen or nitrogen molecule. For single-charged atomic ions the existence of a process of breaking away of a single electron from the ion casing has been established (stripping of ions). Cross-section of the process is greater for ions of heavy elements. An evaluation was carried out of the effective cross-section of the ions H(+)2, H(+)3, N(+)2. (Author)
