      Giant resonances are collective excitations of the atomic nucleus, a typical quantum many-body system. The study of these fundamental modes has in many respects contributed to our understanding of the bulk behavior of the nucleus and of the dynamics of non-equilibrium excitations. Although the phenomenon of giant resonances has been known for Reviews: 1. Metal cluster (MC) is a bound system consisting of atoms of some metal. The amount of atoms can vary from a few to many thousands. Some MC, mainly of alkali (Li, K, Na, ) and n.

      Abstract: The compression-mode giant resonances, namely the isoscalar giant monopole and isoscalar giant dipole modes, are examples of collective nuclear motion. Their main interest stems from the fact that one hopes to extrapolate from their properties the incompressibility of uniform nuclear matter, which is a key parameter of the nuclear Equation of State (EoS). The collective model of the giant resonances is described. The dipole vibrations are discussed in greater detail and applied to both spherical and deformed nuclei. In a consistent expansion of the model the collective-charge vibrations are coupled to the low-energy nuclear-surface vibrations. The implications of this dynamical treatment on the photoabsorption cross section are discussed and.

The giant resonances, being collective phenomena, are influenced by and thus constrain properties of bulk nuclear matter. The “breathing” mode, the isoscalar giant monopole resonance (ISGMR), is a compressional mode and allows for a direct experimental constraint on the nuclear incompressibility. To measure these modes, the group uses deep.

Giant resonances 1 are broad, resonance-like structures in excitation functions with large cross sections, excited by incident γ rays as well as in inelastic particle reactions such unusually large width is a consequence of the high excitation energy with.

Giant resonance is a high-frequency collective excitation of atomic nuclei, as a property of many-body quantum the macroscopic interpretation of such an excitation in terms of an oscillation, the most prominent giant resonance is a collective oscillation of all protons against all neutrons in a nucleus.

If all the intrinsic states. Landau's theory of collective motion in Fermi systems is applied to the giant resonances in nuclei. It is shown that the restoring forces associated with these modes can be simply expressed in terms of local Landau parameters. Explicit expressions are given for the energies of the monopole and quadrupole modes.

This volume focuses on recent developments in nuclear physics, with emphasis on the investigation of processes connected with large-amplitude collective motion in nuclei, such as heavy-ion fusion, giant multipole resonances, and nuclear fission and fragmentation.

To that end, we employ a spectral analysis of time-dependent Hartree-Fock (TDHF) dynamics using Skyrme forces. Based on TDHF calculations over a wide range of excitation amplitudes, we explore the collectivity and degree of harmonic motion in these modes.

Such is very much the case with atomic 'giant resonances'. For a start, their name itself was borrowed from the field of nuclear collective resonances.

The compression-mode giant resonances, namely the isoscalar giant monopole and isoscalar giant dipole modes, are examples of collective nuclear motion. Their main interest stems from the fact that one hopes to extrapolate from their properties the incompressibility of uniform nuclear matter, which is a key parameter of the nuclear Equation of State (EoS).

Our understanding of these issues. Theories for giant resonances date back to when a sim-ple hydrodynamical interpretation of protons oscillating against the neutrons was used [7, 8]. Later on microscopic calculations were developed based on the linear response theory [9]. Nowadays, an e ort is being undertaken to describe nuclear collective motion with more elaborated.

Time-dependent and self-consistent calculations that reproduce experimental data on monopole resonances in Pb show that the motion of the collective coordinate is regular for isoscalar. Abstract: In the last 10 years, we have observed an important increase of interest in the application of time-dependent energy density functional theory (TD-EDF).

This approach allows to treat nuclear structure and nuclear reaction from small to large amplitude dynamics in a unified framework.
