12458 IUPAC Gold Book - kinetic energy release distribution 10.1351/goldbook.12458 12458 current acronym: KERD 1 Distribution of values of translational energies in the center-of-mass reference for an ensemble of metastable ions undergoing a specific dissociation reaction. In this context, kinetic energy is interpreted as translational, rather than vibrational or rotational, kinetic energy. mass-analyzed ion kinetic energy spectrometry (MIKES) https://goldbook.iupac.org//terms/view/12476 PAC, 2013, 85, 1515.
