Modes of decay in neutron-rich nuclei
  We calculate the ground, first intrinsic excited states and density distribution for neutron-rich thorium and uranium isotopes, within the framework of relativistic mean field(RMF) approach using axially deformed basis. The total nucleon densities are calculated, from which the cluster-structures inside the parent nuclei are determined. The possible modes of decay, like {\alpha}-decay and \b{eta} -decay are analyzed. We find the neutron-rich isotopes are stable against {\alpha}-decay, however they are very much unstable against \b{eta} -decay. The life time of these nuclei predicted to be tens of second against \b{eta} -decay.
