Nuclear charge radii and shape evolution of Kr and Sr isotopes with the deformed relativistic Hartree-Bogoliubov theory in continuum

Nuclear mass table in deformed relativistic Hartree–Bogoliubov theory in continuum, I: Even–even nuclei

“…With the continuum, the deformation, the pairing correlation and the blocking effects self-consistently included, the successful exploration of the DRHBc theory in the nuclear chart has been extended to even-odd nuclei, and the corresponding mass *: Since PC-PK1 is a non-linear density functional, it encounters high density instability in 24,25,26 Mg and 26,28 Si, similar to that in 12 C by NL1 [78]. †: Some nuclei have positive S 2n , S 2p , and S n as well as negative λ n and λ p , but are unbound against multi-nucleon emission.…”

“…Ref. [25], with the DRHBc + 2DCH method adopted [24], the rms deviation of E rot for Kr and Sr isotopes is reduced from 3.0 MeV to 1. 8 MeV with the rotational correction energies, and further reduced to 1.2 MeV with the dynamical correction.…”

“…Based on the DRHBc theory, the angular momentum projection has been implemented to investigate the low-lying spectra of neutronrich magnesium isotopes [19,20], and the finite amplitude method has been developed to study the isoscalar giant monopole resonance in exotic nuclei [21]. The optimization of the DRHBc theory has been studied for the multipole expansion of nuclear densities [22], the Dirac Woods-Saxon (DWS) basis optimized [23], and the dynamical correlation energy and the nuclear shape evolution explored by the two-dimensional collective Hamiltonian (2DCH) [24,25].…”

Evolution of N = 20, 28, 50 shell closures in the 20 ≤ Z ≤ 30 region in deformed relativistic Hartree-Bogoliubov theory in continuum*

“…It has recently been applied to construct a mass table for even-even nuclei [40], and the mass table for odd-A and odd-odd nuclei is under construction [41]. In addition, many interesting studies have been performed, such as the impact of deformation effects on the location of the neutron drip line [42], the dynamical correlation energy with a two-dimensional collective Hamiltonian [43], the multipole expansion of densities [44], the rotational mode of deformed halo nuclei [45,46], the bubble structure and shape coexistence [47,48], the peninsulas of stability beyond the two-neutron drip line [49−51], the optimization of the Dirac Woods-Saxon (WS) basis [52], the shell closure at in the neodymium isotopic chain [39,41], the collapse of the shell closure in the newly discovered [37], the oddeven staggering and kink structures of charge radii of isotopes [53], the prolate-shape dominance in atomic nuclei [54], the nuclear charge radii and shape evolution of Kr and Sr isotopes [55], and the one-proton emission of Lu using the DRHBc+WKB approach [56]. In this work, we apply the DRHBc theory to study the isotopes.…”
