Relativistic density functional theory in 3D lattice: Fission barriers with PC-PK1

Based on the relativistic density functional theory method in three-dimensional lattice space, this paper calculates the deformation and energy of actinide nuclei in groundstates, fission internal barriers, fission external barriers, and isomeric states The data set includes the deformations and energies of seven actinide nuclei, namely 232U, 234U, 236U, 238U, 236Pu, 238Pu, and 240Pu, when they are in fission inner and outer barriers, as well as in their isomeric states.
