“…with a gas atom [4][5][6][7][8]. For light projectiles the semiclassical Binary Encounter Approximation (BEA) [9,10] and quantum mechanical Born approximation calculations [11] are reproducing these data reasonably well in a number of cases [8,107. For projectiles heavier than argon no data have been published, and there are no theoretical predictions for the electron energy spectra available.…”

Abstract. Secondary electron spectra up to 3.5keV electron energy arising from the passage of alpha particles and a52Cf fission products through a 2 gg/cm 2 carbon foil are measured for a forward (42 ~ and a backward (138 ~ angle of emission. The forward spectra induced by alpha-particles are compared to binary encounter calculations and to a gas target spectrum. Systematic differences in the shapes of the alpha particle and the fission product induced spectra are discussed. Total yields and mean energies of the secondary electrons are derived from the spectra.

“…This tradition was continued with Thomas' genius analysis of electron capture in 1927 [15] and later with the binary encounter model for ionization [16]. For problems with one active electron, the "classical trajectory Monte Carlo (CTMC) Method" [17] was developed as an efficient algorithm with, quite often, quantitative predictive power.…”

“…Utilization of the latter leads to the appearance of "tails" in the energy distributions for high-energy &electrons. But application of the cross-section [7] in the Monte-Carlo calculation is associated with great difficulties and therefore a simpler expression was used [9], since the energy dependence of the differential cross-section da/dQ(e) ( E is the kinetic energy of the %electron) for all cross-sections turned out to be the same da/ds = 1/82, An arbitrary choice of the &electron energy was performed according to the formula given in [9], for which a simple algorithm may be suggested, based upon Neiman's rejection method. The direction in which a S-electron is emitted is determined from kinematic relations.…”

Detailed characteristics of secondary electron emission from silicon after bombardment by multiply charged ions Al, C, 0, Ca, Si, Fe with energies up to 20 MeV/nucleon are deduced from MonteCarlo simulations. The calculated integral yields 7 in forward direction to approach the 7-Zeff law. The discrepancies between calculated and experimental data for fission fragments are discussed. Limits for ion charge resolution by secondary particle counting are obt,ained.Ausfuhrliche Charakteristiken der Sekundarelektronenemission von Silizium nach dem BeschuB mit vielfach geladenen Al-, C-, 0-, Ca-, Si-, Fe-Ionen mit Energien bis zu 20 MeV/Nukleon werden aus Monte-Carlo-Simulationen abgeleitet. Die berechneten Integralausbeuten 9 in Vorwiirtsrichtung niihern sich dem r]-Z,ff-Gesetz an. Die Differenzen zwischen berechneten und experimentellen Werten fur Spaltungsbruchstiicke werden diskutiert. Die Grenzen fur die Suflosung der Ionenladung durch Zahlen der Sekundiirteilchen werden aufgezeigt.
