General expression for the density effect for the ionization loss of charged particles

摘要: The equations for the density-effect correction $\ensuremath{\delta}(X)$ ionization loss as given in a previous paper have been extended to case where $\ensuremath{\delta}({X}_{0})\ensuremath{\equiv}{\ensuremath{\delta}}_{0}g0$. Here ${X}_{0}$ is lower limit of range ${X}_{0}lXl{X}_{1}$, particularly simple expression applies; $X={log}_{10}(\frac{p}{{m}_{0}c})$, $p$ momentum and ${m}_{0}$ mass incident particle. ${\ensuremath{\delta}}_{0}g0$ applies directly calculation conductors (metals).
