Double ionisation of He by 3.6 MeV/u Au impact is investigated in a kinematically complete experiment using an integrated multi-electron recoil-ion momentum spectrometer (reaction microscope). Surprisingly, the final-state correlation between the recoiling He target ion momentum and the momenta of both emitted electrons is found to be the strongest among the various two-body correlations. On th...

Fully acetylated methyl x-deoxy-x-fluoro-alpha-D-glucopyranosides have been studied using electron impact and ammonia chemical ionisation mass spectrometry. Mass analysed metastable ion kinetic energy spectroscopy (MIKE), collisional activation (CID), and accelerated voltage scanning have been used to evaluate complete fragmentation schemes. Characteristic differences in the fragmentation of po...
