## Translational energy spectrometry measurements have been made on Hei ions resulting from 3 keV double-electron capture collisions between He: and Ns. The endoergic energy defect for this reaction is measured to be 43 eV. Potential energy curves have been computed for He: (X Ix+), HeF(Z\*) and
Negative ions of small oligonucleotides are shown to undergo collisional and collision-free neutralization following matrix assisted laser desorption and ionization (MALDI). Using a modified MALDI time of flight instrument, approximate collisional cross sections and collision-free lifetimes have bee
