    "abstract": "The series of Uranium isotopes with $N=154 \\sim 172$ around the magic number\nN=162/164 are identified to be thermally fissile. The thermal neutron fission\nof a typical representative $^{249}$U of this region amenable to synthesis in\nthe radioactive ion beam facilities is considered here. Semiempirical study of\nfission barrier height and width shows this nucleus to be infinitely stable\nagainst spontaneous fission due to increase in barrier width arising out of\nexcess neutrons. Calculation of probability of fragment mass yields and\nmicroscopic study in relativistic mean field theory, show this nucleus to\nundergo a new mode of thermal fission decay termed {\\it multifragmentation\nfission} where a number of prompt scission neutrons are simultaneously released\nalong with the two heavy fission fragments.",
