摘　　要：一、前言 对^(235)U热中子裂变已经作了充分的研究,裂变产物的产额作了广泛的测量,并对实验数据进行了多次编评。但是对于其它单能中子诱发^(235)U裂变研究还远远不够,尤其是keV能区的中子更是如此。J.G.Cuninghame等测量了130-1700keV中子诱发^(235)U裂变中一些核素的产额。但是低于130keV中子诱发的裂变研究,文献中未见过报道。The fission yields of 99Mo, 132Teand 140Ba from 235U fission induced by 24.4 keV neutrons are measured radiochemically. The neutron source is an iron filter neutron beam from a swimming pool reactor. The fission number is recorded by polycarbonate film as a fission track recorder, which is immersed in liquid uranium standard targets.
