✦ Synopsis

Translational energy losses AE in keV-collisions have been determined for peptide ions and for caesium iodide cluster ions subsequently decomposing to specific fragment ions, and the dependences of tbese energies upon trammission have been investigated. Parent ions decomposing to certain fragment iom exhibit energy losses which are independent of transmission, while parent ions associated with other fragment ions show strong depedence of energy loss u p transmission. These findings are interpreted in terms of energy redistributions of tens of eV taking place in single collisions via direct momentum-transfer.
