METHOD     (TOF) After leaving the fission source the neutrons    1479800200004 
           traverse a flight path of 80 cm before striking the    1479800200005

DETECTOR   (SCIN) This detector consisted of a 1 15/16 in. x 1    1479800200007 
           1/2 in. piece of 8 plastic scintillator mounted on a   1479800200008

METHOD     (REC) For the proton recoil method, emulsions were     1479800300004 
           exposed to the Cf252 source in such a manner that the  1479800300005 
           neutrons entered the emulsions at an angle of 5-10     1479800300006
