Velocity map imaging with non-uniform detection: Quantitative molecular axis alignment measurements via Coulomb explosion imaging.

摘要: We present a method for inverting charged particle velocity map images which incorporates non-uniform detection function. This is applied to the specific case of extracting molecular axis alignment from Coulomb explosion imaging probes in probe itself has dependence on orientation often removes cylindrical symmetry experiment and prevents use standard inversion techniques recovery distribution. By incorporating known function, it possible remove angular bias process invert image allow quantitative measurement degree alignment.
