Abstract
The fragmentation of the methane ion has been measured as a function of ion internal energy in the range 12-40 eV using the fixed wavelength photoelectron photoion coincidence (PEPICO) technique, with He Iα and He IIα light. We confirm that the fragmentation of methane ions in the A state is not well represented by statistical calculations. In the satellite states between the A state and 33 eV, the ion breaks into small fragments; in satellite states above 33 eV the fragmentation is related to the behaviour of doubly-charged methane.
