Multifragmentation Fission in Neutron-rich Uranium and Thorium Nuclei

Abstract

The structural properties of the recently predicted thermally fissile neutron-rich Uranium and Thorium isotopes are studied using the relativistic mean field formalism. The investigation of the new phenomena of multifragmentation fission is analyzed. In addition to the fission properties, the total nuclear reaction cross section which is a measure of the probability of production of these nuclei is evaluated taking 6,11Li and 16,24O as projectiles. The possible use of nuclear fuel in an accelerator based reactor is discussed which may be the substitution of 233,235U and 239Pu for nuclear fuel in near future.
