Stopping Power of Various Gases for Lithium Ions of 100-450-kev Kinetic Energy
Abstract
The stopping power, expressed in electron volts per atom of gas per square centimeter has been measured in H2, He, air, and argon for lithium ions in the kinetic energy range 100-450 kev. Collisions which would have deviated the lithium ions as much as 10-3 radian would have removed them from the detector aperture, so that the measured stopping power arises entirely from electronic collisions. The following results were obtained: <colspec colname="Col1"/><colspec colname="Col2"/><colspec colname="Col3"/><colspec colname="Col4"/><colspec colname="Col5"/> ELi Atomic stopping power in units of 10-15 ev×cm2/atom (kev) H2 He Air Argon 150 6.4 5.7 20.2 40.1 250 10.1 9.9 29.2 53.8 350 11.4 13.1 34.1 66.2 450 13.4 15.3 43.5 73.7
