The Energy Loss of Low Energy Protons in Some Gases

Experimental values for the energy loss of protons in H₂, He, N₂, O₂, A, Kr, H₂O, CO₂, and CCl₄ have been obtained in the region from 10 to 80 kev. The energy loss () can be expressed for the elementary gases measured in terms of a single curve, with two constants =Lf (ME). The energy loss per atom is independent of the target density over the range 0 to 1. 5-mm Hg, and the energy loss for compound gases is equal to the sum of their components.
