For ionizing uncharged particles of a give … For ionizing uncharged particles of a given type and energy, the differential quotient of Rtr with respect to l. Where Rtr is the mean energy that is transferred to kinetic energy of charged particles by interactions of the uncharged particles of incident radiant energy R in traversing a distance l in the material of density rho, divided by rho and Rerial of density rho, divided by rho and R +
