Transfer excitation reactions in fast proton-helium collisions
M. S. Schöffler, H. -K. Kim, O. Chuluunbaatar +9
Continuing previous work, we have measured the projectile scattering-angle dependency for transfer excitation of fast protons (300-1200 keV/u) colliding with helium (p+He $\rightar…
Search for isotope effects in projectile and target ionization in swift He on H or D collisions
F. Trinter, M. Waitz, M. S. Schöffler +7
Using the cold target recoil ion momentum spectroscopy (COLTRIMS) technique, we have measured the simultaneous projectile and target ionization in collisions of He projectiles…
Ion impact induced Interatomic Coulombic Decay in neon and argon dimers
H. -K. Kim, H. Gassert, M. S. Schöffler +16
We investigate the contribution of Interatomic Coulombic Decay induced by ion impact in neon and argon dimers (Ne and Ar) to the production of low energy electrons. Our exp…
Vibrationally Resolved Decay Width of Interatomic Coulombic Decay in HeNe
F. Trinter, J. B. Williams, M. Weller +17
We investigate the ionization of HeNe from below the He 1s3p excitation to the He ionization threshold. We observe HeNe ions with an enhancement by more than a factor of 60 whe…
2D electron momentum distributions for transfer ionization in fast proton Helium collisions
M. S. Schoeffler, O. Chuluunbaatar, S. Houamer +9
The momentum distribution of the electron in the reaction p+He H + He + is measured for projectile energies =300 and 630 keV/u at very small scatterin…
Probing the tunneling site of electrons in strong field enhanced ionization of molecules
J. Wu, M. Meckel, L. Ph. H. Schmidt +7
Molecules show a much increased multiple ionization rate in a strong laser field as compared to atoms of similar ionization energy. A widely accepted model attributes this to the a…
