Line Shapes in Time-of-Flight Mass Spectrometry: Application of a Genetic Algorithm — •Christof Maul — Institut für Physikalische und Theoretische Chemie, TU Braunschweig, Hans-Sommer-Str. 10, 38106 Braunschweig

A data analysis method is presented which is based on the application of a genetic algorithm to a forward convolution procedure which finds the best three-dimensional product momentum distribution from one-dimensional experimental data as typically obtained in reaction dynamics experiments utilising laser induced fluorescence or resonance enhanced multi-photon ionisation combined with time-of-flight measurements. The high performance of the method is demonstrated for a complex product distribution exhibiting a velocity dependent anisotropy behaviour.
