“…For heavy elements at low energy, the nuclei will have several electrons attached (Ahlen, 1980). For example, the effective charge of an iron (Z = 26) nucleus at 20 MeV/nucleon is only +24.9.…”

Abstract. The Cosmic Ray Isotope Spectrometer is designed to cover the highest decade of the Advanced Composition Explorer's energy interval, from 50 to 500 MeV/nucleon, with isotopic resolution for elements from Z ' 2 to Z ' 30. The nuclei detected in this energy interval are predominantly cosmic rays originating in our Galaxy. This sample of galactic matter can be used to investigate the nucleosynthesis of the parent material, as well as fractionation, acceleration, and transport processes that these particles undergo in the Galaxy and in the interplanetary medium.Charge and mass identification with CRIS is based on multiple measurements of dE=dx and total energy in stacks of silicon detectors, and trajectory measurements in a scintillating optical fiber trajectory (SOFT) hodoscope. The instrument has a geometrical factor of 250 cm 2 sr for isotope measurements, and should accumulate 5 10 6 stopping heavy nuclei (Z 2) in two years of data collection under solar minimum conditions.

“…The mean energy loss is given in MeVIcm, the density p is considered in g/cm3, here Ek is the electron kinetic energy in MeV, mc2 = 0.51 MeV, and I (MeV units) are the ionization potentials which are listed in the literature (Ahlen, 1980). The parameter dimensionless 6 is known as a density effect.…”

“…The parameter dimensionless 6 is known as a density effect. The semiempirical form of 6 originally proposed by Sternheimer (1952) is still used (Ahlen, 1980). The parameter p is the velocity of the electron divided by the velocity of the light.…”

The photofission proces has been recently considered for the production of neutron rich isotopes and the development of radioactive beams. The radioprotection bazard should he sîudied accordingly. A survey of the radiative electron energy loss theory is reported in order to estimate numerically the hremsstrahlung production of thick targets. The resulted bremsstrahlung angdar and energy theoretical distributions delivered from W and UCx thick converters are presented and compared with previous resuits. This study is focused on initiai kinetic energies of the electron heam included in the range 3-60 MeV, suitable for the production of large photon yields able to induce the 238U fission. The source term for 50 MeV incident electrons is reported for radioprotection purposes. RÉSUMÉ
