Description
Energy-loss distributions for Cl ions in Ar-CH4 and isobutane were measured at incident energies Eo = 9.4, 17.1, 27.1 and 39.4 MeV up to relative energy losses ΔE/Eo <= 0.7. The full widths at half maximum are larger than predicted by the Landau-Vavilov-theory by more than a factor two. A semiempirical formula is derived which reproduces well all data measured. Reasonable agreement is obtained between this formula and other energy straggling data of heavy ions reported in the literature. (orig.)
Abstract (German)
Die Energieverlustverteilungen der Chlorionen in Ar-CH4 und Isobutan wurden bei Einschussenergien von Eo = 9.4, 17.1, 21.1 und 39.4 MeV bis zu relativen Energieverlusten von ΔE/Eo <= 0.7 gemessen. Die volle Halbwertsbreite ist mehr als zweimal so breit wie die Vorhersage der Landau-Vavilov-Theorie. Eine semiempirische Formel wird abgeleitet; sie stimmt mit allen gemessenen Daten gut ueberein. Befriedigende Uebereinstimmung erhaelt man auch zwischen dieser Formel und anderen Energie-straggling-Daten fuer schwere Ionen, die in der Literatur angegeben sind. (orig.)Additional details
