The impact of particle-vibration coupling and polarization effects due to deformation and timeodd mean fields on single-particle spectra is studied systematically in doubly magic nuclei from low mass 56 Ni up to superheavy ones. Particle-vibration coupling is treated fully self-consistently within the framework of relativistic particle-vibration coupling model. Polarization effects due to deformation and time-odd mean field induced by odd particle are computed within covariant density functional theory. It has been found that among these contributions the coupling to vibrations makes a major impact on the single-particle structure. The impact of particle-vibration coupling and polarization effects on calculated single-particle spectra, the size of the shell gaps, the spin-orbit splittings and the energy splittings in pseudospin doublets is discussed in detail; these physical observables are compared with experiment. Particle-vibration coupling has to be taken into account when model calculations are compared with experiment since this coupling is responsible for observed fragmentation of experimental levels; experimental spectroscopic factors are reasonably well described in model calculations.

“…In this method, chargedparticle decay modes, such as α, proton, and superallowed β-ray emission, as well as isomeric decay provide highly selective tagging of the prompt γ rays from a nucleus of interest. Beta-delayed proton (βp) emission is one of the tagging methods and it has been successfully applied in the study of single neutron states outside doubly-magic 100 Sn where one γ ray was identified [23]. In an earlier study of 109 Te, singles γ-ray spectra (Figs.…”

Excited states have been observed for the first time in the neutron-deficient nucleus 117 Ba using the Recoil-Decay Tagging technique following the heavy-ion fusion-evaporation reaction 64 Zn( 58 Ni, 2p3n)117 Ba. Prompt γ rays have been assigned to 117 Ba through correlations with β-delayed protons following the decay of A = 117 recoils. Through the analysis of the γ-γ coincidence relationships, a high-spin level scheme consisting of two bands has been established in 117 Ba. Based on the systematics of the level spacings in the neighboring barium isotopes, the two bands are proposed to have νh 11/2 [532]5/2 − and νd 5/2 [413]5/2 + configurations, respectively. The observed band-crossing properties are interpreted in the framework of cranked shell model.

“…First of all, nuclei approaching the N = Z line are believed to be candidates for a new type of (deuteron-like) pairing, but different theories disagree on this matter [1][2][3]. Second, the energies of the single-particle levels in 101 Sn are widely debated due to two contradictory experimental claims [4,5]. Third, a new spinaligned isoscalar (T = 0) proton-neutron coupling scheme has recently been proposed to be important in nuclei in the vicinity of 100 Sn [6].…”
