“…Only few experimental data are available (Bimbot et al 1983). The comparison shows that the best agreement is obtained if it is taken into account that the ion's effective charge Z* is not only a function of its energy but also of the absorbing medium (Bimbot et al 1983). It appears from this that the recent compilation by Hubert et al (1980) is the most reliable.…”

The biological effects of irradiation with ions of masses larger than 40 and energies up to 20 MeV per atomic mass unit are reviewed. The objects are viruses, bacterial spores, yeast and mammalian cells. Experimental parameters include loss of colony forming ability, induction of mutants, chromosomal aberrations, cell cycle progression, inhibition of biochemical activities and the formation of strand breaks. Some of the pertinent physical questions--e.g. track structure--are also discussed. It is shown that with very heavy ions the biological effectiveness is no longer unambiguously related to a single parameter like l.e.t. or Z*2/beta 2 but depends strongly on ion energy. This points to the importance of far-reaching delta-electrons. The analysis indicates also that even with very high l.e.t., cells are not killed by the passage of a single particle through their nucleus. Possible implications of the findings for fundamental radiation biology are outlined.

a b s t r a c tIn the slowing-down of heavy ions in materials, the standard description by Lindhard and Scharff assumes the electronic stopping cross section to be proportional to the projectile speed v up to close to a stopping maximum, which is related to the Thomas-Fermi speed v TF . It is well known that strict proportionality with v is rarely observed, but little is known about the systematics of observed deviations.In this study we try to identify factors that determine positive or negative curvature of stopping cross sections on the basis of experimental data and of binary stopping theory. We estimate the influence of shell structure of the target and of the equilibrium charge of the ion and comment the role of dynamic screening.

“…The available experimental stopping powers for Ar, Kr, Au and U ions in isobutane (258 experimental points in the energy range from 0.1 to 15 MeV/nucleon) [3, 9,[12][13][14] were used to determine the parameters for gaseous media, whereas data relative to the same projectiles but in aluminum (121 experimental points for energies from 0.5 to 15 MeV/nucleon) [3,9,[15][16][17][18][19][20] were used for solid media.…”
