Neon dimer ions undergo spontaneous dissociation (metastable decay) several microseconds after formation by electron impact ionization of neon clusters. In this contribution we compare the kinetic energy release distribution (KERD) of the previously

We have measured kinetic-energy-release distributions (KERD) for spontaneous dissociation of electronically excited dimer ions of krypton and xenon, formed by electron impact ionization of neutral precursors. The data cannot be reconciled by decay of

We present absolute partial electron impact ionization cross sections for propene in the electron energy range between threshold and 1000 eV measured with a two sector field double focussing mass spectrometer. Ion beam profiles have been measured at

We have measured the kinetic energy release distributions for unimolecular C 2 loss from singly and multiply charged endohedral La@C 80 z + and La@C 80 z + ions for charge states z = 1–3. Using finite heat bath theory, we deduce the dissociation en

We used the semi-classical Deutsch-Mark (DM) formalism to calculate absolute electron-impact ionization cross sections of excited Ne atoms from threshold to 1000 eV. Excited states of Ne where the outermost valence electron is excited to states with

Doubly charged ions produced by electron impact ionization of toluene undergo metastable decomposition. We have determined decay channels for C 7 H y 2 + ( y = 6 – 8 ) and the average kinetic energy release (KER) by applying the MIKE scan technique

Metastable fractions for the dissociation of fullerene cations C n + → C n - 2 + + C 2 ( 42 ⩽ n ⩽ 70 ) have been measured in a three-sector-field mass spectrometer. They have been determined with the same experimental setup as the kinetic energ
