摘要: The U235 fission yield curve for uranium fuel rods from mass number 143 to 160 is measured utilizing spectrometric techniques. Eight percentage yields are assumed in this region, and on the basis of measurements neodymium, samarium, europium, gadolinium isotopes, nine other obtained. resulting smooth. Based same assumptions which give smooth following cross sections half lives Cross Sections: Sm149, 47,000 barns; Sm151, 7200 Gd155, 41,000 Gd157, 59,500 barns. Half lives: 61147, 2.26 yr.; 122 yr.
