DENSITY EFFECT FOR THE IONIZATION LOSS OF CHARGED PARTICLES

The reduction in the ionization loss of charged particles due to the polarization of the medium (density effect) has been evaluated for several additional substances, in particular for ${\mathrm{Li}}_{2}$${\mathrm{B}}_{4}$${\mathrm{O}}_{7}$, ${\mathrm{Al}}_{2}$${\mathrm{O}}_{3}$, Ca${\mathrm{F}}_{2}$, NaI, CsI, lithium aluminosilicate glass, and a ${\mathrm{H}}_{2}$-Ne mixture used in bubble chambers.
