We provide a short review of the current status of the nuclear energy density functional (EDF) and the theoretical results obtained for properties of nuclei and nuclear matter. We will first describe a method for determining the parameters of the EDF, associated with the Skyrme type effective interaction, by carrying out a Hartree-Fock (HF)-based fit to the extensive set of data of ground-state properties and constraints. Next, we will describe the fully self-consistent HF-based random-phase-approximation (RPA) theory for calculating the strength functions () SE and centroid energies CEN E of giant resonances and the folding model (FM) distorted wave Вorn approximation (DWBA) to calculate the excitation cross-section of giant resonances by α scattering. Then we will provide results for: (i) the Skyrme parameters of the KDE0v1 EDF; (ii) consequences of violation of self-consistency in HF-based RPA; (iii) FM-DWBA calculation of excitation cross-section; (iv) values of the CEN E of isoscalar and isovector giant resonances of multipolarities 03 L  for a wide range of spherical nuclei, using 33 EDFs associated with the standard form of the Skyrme type interactions, commonly employed in the literature; and (v) the sensitivities CEN E of the giant resonances to bulk properties of nuclear matter (NM). We also determine constraints on NM properties, such as the incompressibility coefficient and effective mass, by comparing with experimental data on CEN E of giant resonances.

“…In these two decades, inelastic α scattering (α, α ) has been extensively investigated to obtain information about excited states. Especially, the (α, α ) reaction has been utilized as a sensitive probe for isoscalar monopole (IS0) and IS1 transitions of excited states as well as giant resonances in various nuclei [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. It is also a useful tool to search for new cluster states because cluster excitations often have strong inelastic transitions [20,[33][34][35][36][37][38].…”

+ , 1 − , 2 + , and 3 − excitations of 28 Si are investigated via proton and α inelastic scattering off 28 Si. The structure calculation of 28 Si is performed with the energy variation after total angular momentum and parity projections in the framework of antisymmetrized molecular dynamics (AMD). As a result of the AMD calculation, the oblate ground and prolate bands, 0 + and 3 − excitations, and the 1 − and 3 − states of the K π = 0 − band are obtained. Using the matter and transition densities of 28 Si obtained by AMD, microscopic coupled-channel calculations of proton and α scattering off 28 Si are performed. The proton-28 Si potentials in the reaction calculation are microscopically derived by folding the Melbourne g-matrix N N interaction with the AMD densities of 28 Si. The α-28 Si potentials are obtained by folding the nucleon-28 Si potentials with an α density. The calculation reasonably reproduces the observed elastic and inelastic cross sections of proton and α scattering. Transition properties are discussed by combining the reaction analysis of proton and α scattering and structure features such as transition strengths and form factors. The isoscalar monopole and dipole transitions are focused.

“…Here, we will only reiterate the major benefit provided by the ion-optics of Grand Raiden in vertical focusing mode: this arrangement renders it possible to subtract out the contributions from the instrumental background events, which underlie the true inelastic scattering spectra, based on their detected vertical positions. This feature is unique to measurements of the ISGMR at RCNP, as otherwise one is forced to account for the instrumental background and physical continuum in a phenomenological way, often with ill effect on the extracted ISGMR strength [27,29,30,31,32,33]. Inelastic-scattering data were extracted over broad angular (0 • -10 • in the laboratory frame) and excitation-energy (10-32 MeV) ranges.…”

Compressional-mode resonances in the molybdenum isotopes: Emergence of softness in open-shell nuclei near A=90

Why are the tin isotopes soft? " has remained, for the past decade, an open problem in nuclear structure physics: models which reproduce the isoscalar giant monopole resonance (ISGMR) in the "doubly-closed shell" nuclei, 90 Zr and 208 Pb, overestimate the ISGMR energies of the open-shell tin and cadmium nuclei, by as much as 1 MeV. In an effort to shed some light onto this problem, we present results of detailed studies of the ISGMR in the molybdenum nuclei, with the goal of elucidating where-and how-the softness manifests itself between 90 Zr and the cadmium and tin isotopes. The experiment was conducted using the 94,96,98,100 Mo(α, α ) reaction at E α = 386 MeV. A comparison of the results with relativistic, self-consistent Random-Phase Approximation calculations indicates that the ISGMR response begins to show softness in the molybdenum isotopes beginning with A = 92.
