The incorporation of impurities into solids by bombardment with energetic ions is a non-
equilibrium process which can result in intriguing near-surface property changes. This …

On attending a conference on the Jovian satellites at UCLA, I heard Lou Lanze rotti
vigorously present the exciting data on the sputtering of water ice by Me V protons taken with …

Radiation synthesis has been proposed as a mechanism for changing the nature of the
outer few meters of ice in a comet stored 4.6 billion years in the Oort cloud and may explain …

Abstract The International Ultraviolet Explorer (IUE) spacecraft has obtained observations of
the galilean satellites over the past 2 years which fortuitously span the periods of the …

Water ice is abundant both astrophysically, for example, in molecular clouds, and in
planetary systems. The Kuiper belt objects, many satellites of the outer solar system, the …

Plasma and UV photon bombardment of an icy object in the outer solar system can lead to
ejection of atoms and molecules from the surface which can, in turn, produce an extended …

We measured the total sputtering yield Y of amorphous water ice at 80K for 0.35–4keV He
and Ar ions. We found that Y depends linearly on the elastic stopping cross section at low …

Recent data on the desorption of large biomolecules by fast (MeV) ions are examined with
use of the ion-track model derived from ''hit''theory commonly used in radiation biology. In …

Molecular oxygen produced by the decomposition of icy surfaces is ubiquitous in Saturn's
magnetosphere. A model is described for the toroidal O2 atmosphere indicated by the …

The erosion of water ice films by fast H and He ions has been found to depend on the
electronic energy loss of the ion. At low temperatures the erosion yield is temperature …
