“…The finite-range interactions have been improved by adding the tensor term [96,97]. This important addition considerably extended the set of the EDF used [98][99][100][101][102][103][104][105][106][107][108][109]. However, this scheme is found to be only partially successful.…”

Self-consistent methods for the structure of heavy and superheavy nuclei are reviewed. The construction and application of energy-density functionals are discussed. The relationship between the self-consistent methods and microscopic-macroscopic approaches is considered on the mean-field level. The extraction of single-particle potentials from the energy-density functional is described. The isotopic dependence of nucleon distributions and its influence on the nucleus-nucleus interaction is analyzed. As a new additional condition we introduce that the energy-density functional must describe the heights of the Coulomb barriers in nucleusnucleus interaction potentials, thus imposing constraints on the properties of the functional at low matter densities. The self-consistent methods are applied to describe the quasiparticle structure, cluster radioactivity, and fission of the heaviest nuclei. These methods are used to predict the probabilities of β-delayed multi-neutron emission and half-lives of β-decays and electron captures in heavy and superheavy nuclei. The predicted properties of superheavy nuclei are used to estimate the production cross-sections of superheavy nuclei in complete fusion reactions. Contents

“…The choice of this system was partially motivated by a recent extensive study of quasifission for the same system using the SLy4d interaction [49]. Static Hartree-Fock (HF) calculations result in a spherical density distribution for 48 Ca, while 249 Bk shows prolate quadrupole and hexadecupole deformation, in agreement with experimentally observed properties. In practice, TDHF calculations are performed by placing the two static HF solutions obtained for the target and projectile at a distance of 28 fm apart assuming that the two nuclei reached this separation on a Coulomb trajectory and the relevant velocities are used to boost the nuclei.…”

“…Recently, time-dependent Hartree-Fock (TDHF) theory has proven to be an excellent tool for studying quasifission dynamics [34][35][36]. In particular, massangle distributions and final fragment total kinetic energies (TKE) [15,16,[37][38][39][40][41][42][43][44][45][46][47][48][49][50][51] are in good agreement with experimental observations. Furthermore, TDHF studies of quasifission dynamics have taught us that dynamics itself may be dominated by shell effects [34,52].…”

“…During the past decade it has become numerically feasible to perform TDHF calculations on a 3D Cartesian grid without any symmetry restrictions and with much more accurate numerical methods [67][68][69]. In this paper, we focus on quasifission in the reaction 48 Ca + 249 Bk. The choice of this system was partially motivated by a recent extensive study of quasifission for the same system using the SLy4d interaction [49].…”
