Fractional independent yields of /sup 133/Xe/sup m/, /sup 133/Xe /sup g/, /sup 135/Xe/sup m/, and /sup 135/Xe /sup g/ have been measured for fission of /sup 233/U, /sup 235/U, /sup 239/Pu, and /sup 242/Am/sup m/ induced by thermal neutrons and for fission of /sup 235/U, /sup 238/U, and /sup 239/Pu induced by 14-MeV neutrons. The same yields have been measured for fission of /sup 235/U induced by degraded fission spectrum neutrons from a bare critical assembly. Some upper limits and ratios of yields of these same isomers have been obtained for the fission of /sup 238/U and /sup 239/Pu by the degraded fission spectrum neutrons. The average angular momentum of these independently formed fission products has been derived from the measured isomer ratios. A method that is particularly well adapted to use with computers for solving the differential equations of radioactive decay and growth is described.
