G. Remmert et al., GAS-PERMEABILITY AND CROSS-SECTION OF LATENT ION TRACKS IN POLYMERS, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 105(1-4), 1995, pp. 197-199
Heavy-ion irradiated foils of Kapton (poly(pyromellitimide), Du Pont)
are investigated by permeation of rare gases. The determined permeabil
ity coefficients are interpreted as the combined coefficients of prist
ine material and of ion tracks. With this assumption, one can deduce a
n effective, gas-specific cross section of the single ion track and it
s permeability coefficient.
