Definition: | quotient of dEΔ by dl, where dEΔ is the energy lost by a charged particle due to electronic collisions in traversing a distance dl, minus the sum of the kinetic energies of all the electrons released with kinetic energies in excess of threshold energy delta LΔ = (dEΔ/dl)
Note 1 to entry: This quantity is expressed in joules per metre. Note 2 to entry: This entry was numbered 393-14-53 in IEC 60050-393:2003.
