摘      要：Charge-changing processes of low-charged ions,used in hydrogen plasma probing by the heavy ion beam probe method,are *** with the ionization of beam ions by plasma electrons and protons,the charge-exchange processes of ions on H atoms and protons are also *** is shown that charge exchange of beam ions on plasma protons and H atoms,which is rarely taken into account,plays an important role in beam–plasma *** data on the cross sections and rates of ionization and charge-exchange processes are presented for Tl+and Tl2+ions,which are frequently used for plasma *** are performed for hydrogen plasma temperatures Te=1 eV–10 keV and densities Ne=1012–1014 cm−3 at relatively low and high ion-beam velocities vb=0.2 and 1.0 a.u.,*** attention is paid to the determination of the electron temperatures at which the charge-exchange processes on H atoms and protons are *** ionization of beam ions by plasma electrons and protons is briefly discussed.
