With small probability in the Binary cascade there is a problem of large energy non conservation. Recently this is seen in p + C12 reaction at 2 GeV when target nucleus is fully disappear and there is no residual nucleus. The probability is about 10^-5. This problem appeared several years ago and is seen in regular test30 runs p + Li reactions seen at 200 MeV. The probability of the problem in Li is about 0.001. 3-momentum is this case is conserved.
Thansk, need to debug...
