THE ABSOLUTE DETERMINATION OF CUMULATIVE YIELD OF SEVERAL NUCLIDES FROM THERMAL NEUTRON AND FISSION SPECTRUM NEUTRON INDUCED FISSION OF ~(235)U

It is reported in this paper that during the thermal neutron fission of 235U,theabsolute cumulative yields of 95Zr, 99Mo and 144Ce as determined by radiochemicalmethod,are(6.39±0.21)％,(6.084±0.16)％and(5.34±0.34)％ respectively.Whereasfor the fission of fission spectrum neutron of 235U,cumulative yields of 95Zr,99Mo,103Ru,106Ru,144Ce and 147Nd are(6.56±0.28)％,(6.38±0.18)％,(3.36±0.18)％,(O.638±O.045)％,(5.28±0.20)％and 2.36±0.11％respectively.
