Advantages of LCID

LCID: A program for simple fitting of energy-resolved reactive cross sections in Threshold Collision-Induced Dissociation (T-CID) experiments. Compared to previous methods available in the literature, the present method has three advantages:

• A more realistic treatment of the electrostatic potential for the approach of the ion to the collision partner leads to a better, nonempirical threshold function, allowing fitting of the cross section over the entire energy range rather than just the onset.
• Treatment of the kinetic shift with a new model for the density-of-states function eliminates the need for explicit entry of frequencies for the starting ion or the transition state without loss of accuracy relative to direct state counts.
• Data fitting using Monte Carlo simulation and a genetic algorithm.
