Empirical track-length range relationship for heavy ions in solid compounds

An empirical relation between track length and range of heavy ions in solid state detectors is obtained for ions of mass M < 141 a.m.u. and initial energies up to 12 MeV/nucleon. This relation is found d to be T 1(E)=S.R(E) where S =δ(1-cρ) [1-ψ (dE/d X)-Cr] in which ( dE/d X)-Cr is the critical stopping power of the detector,ρ is the density of the detector material,and C,δ,and ψ are constants. The relation is examined for six different target materials and is found to be in good agreement with experimental and computed values obtained by different investigators.1 tab., 6 fig
