Continuous electron energy spectra ejected from solid carbon targets bombarded with light and heavy ions

Energy distributions of electrons were measured under an observation angle of 42.3° by bombarding thin carbon foils with protons of 0.5 to 2.5 MeV and with Neon of 10 MeV energies. Comparison of the experiment...

Beam-foil-excited Auger transitions in neon

Energy spectra of electrons ejected from collisions between a carbon foil and Ne projectiles with energies between 1.4 and 20 MeV have been measured. Continuous and discrete electron energy distributions are o...

EquilibriumK-shell excitation of highly ionized neon

Augerelectron emission from foil-excited Ne-ions (6 to 10 MeV beam energy) has been measured. The beam-foil time-of-flight technique has been applied to study electronic transitions of metastable states (delay...

In Search of Collective Electron Emission from Heavy Ion Solid Collisions

The response of the electron plasma of a solid to an energetic (~ Mev/N), penetrating, charged particle manifests itself in electron density fluctuations behind the projectile. The potential ø corresponding to...

Alignment of Fast Molecular Ions

Fast (MeV) molecular projectile ions passing through thin gaseous¹ or solid targets² loose most of their binding electrons in the collision. The remaining molecular fragments are then strongly repelled by the int...

Forskolin and PMA pretreatment of HT₂₉ cells alters their chloride conductance induced by cAMP, Ca²⁺ and hypotonic cell swelling

HT₂₉ cells were preincubated with forskolin (10⁻⁵ mol/l, FORHT) or phorbol 12-myristate 13-acetate (PMA) (10⁻⁷ mol/l, PMAHT) for 20 h, which has been shown previously and is also shown here, to upregulate and dow...

Flufenamate and Gd³⁺ inhibit stimulated Ca²⁺ influx in the epithelial cell line CFPAC-1

The relevant influx pathway for stimulated Ca²⁺ entry into epithelial cells is largely unknown. Using flufenamate (Flu) and Gd³⁺, both known pharmacological blockers of non-selective cation currents in other epit...
