// -January 2009. L. Desorgher
// Put a higher limit on the CS to avoid a high rate of Inverse Photo e- effect at low energy. The very high adjoint CS of the reverse
// photo electric reaction produce a high rate of reverse photo electric reaction in the inner side of a shielding for eaxmple, the correction of this occurrence
// by weight correction in the StepDoIt method is not statistically sufficient at small energy. The problem is partially solved by setting an higher CS limit
// and compensating it by an extra weight correction factor. However when coupling it with other reverse processes the reverse photo-electric is still
// the source of very occasional high weight that decrease the efficiency of the computation. A way to solve this problemn is still needed but is difficult
// to find as it happens in rarea case but does give a weighrt that is outside the noemal distribution. (Very Tricky!)
