Theoretical Range-Energy Values for Protons in Air and Aluminum

In this paper there are presented a discussion of the calculation of range-energy values for protons in air and aluminum and a tabulation of the results. The calculations have been done with considerable accuracy and at sufficiently small energy intervals to allow good graphical interpolation. These figures, as well as those for the rate of energy loss in both cases, have been compiled over a wide range of energies—up to ${10}^{10}$ ev.
