 I ran rdecay01 in singleDecay mode, in two pass (see attached macro montes.txt)

 1- start with Am241.  On which we see branching ratio Am241 --> Np237[59.5 keV] = 85% 

 2- start with Np237[59.5] and plot and print gamma spectrum. The number of gamma of 59.5 keV is 52%

 Then, the combined branching ratio will be 44% (still to high ? ...)
