ANALYSIS   (DECAY) The  number  of  delayed  neutrons  (DN)  was  M075900100018 
            obtained  as the integral of DN decay spectrum (time  M075900100019

            detector efficiency  and  contribution  of  (n,fiss)  M075900100021 
            reactions. The  number  of  fissions   (induced   by  M075900100022 
            photons and  neutrons) was evaluated using the MCNPX  M075900100023
