Damping of isoscalar monopole resonance in highly excited nuclei
The damping mechanism of the isoscalar monopole resonance of the hot nucleus Pb is studied microscopically on the basis of linear response theory. The width Γ of the resonance can be predicted unambiguously, if appropriate values are taken for the damping widths Γsp of single particle motions. Calculations have been done up to the temperature T of 12 MeV, within which Pb can be stable in the th...
متن کاملNuclear matter compressibility from isoscalar giant monopole resonance.
We examine the status of the nuclear matter compressibility K„obtained from experimental data of the strength distribution of the giant monopole resonance in nuclei and employing a least-squares fit to a semiempirical expansion of the nucleus compressibility E~ in A ' '. We present arguments indicating that all the coefficients of this expansion must be determined by a fit to the data. In our a...
متن کاملProperties of the Overtone of the Isoscalar Giant Monopole Resonance
A semi-microscopic approach, based on the continuum-random-phase Approximation (CRPA) method, is applied to describe the main properties (strength function, transition density, direct-nucleon-decay branching ratios) of the overtone of the isoscalar giant monopole resonance. Results of the calculation are presented for 208Pb in comparison with those obtained for the isoscalar monopole and dipole...
متن کاملQuadrupole collectivity in neutron-rich Fe and Cr isotopes.
Intermediate-energy Coulomb excitation measurements are performed on the N ≥ 40 neutron-rich nuclei (66,68)Fe and (64)Cr. The reduced transition matrix elements providing a direct measure of the quadrupole collectivity B(E2;2(1)(+) → 0(1)(+)) are determined for the first time in (68)Fe(42) and (64)Cr(40) and confirm a previous recoil distance method lifetime measurement in (66)Fe(40). The resul...
متن کاملChaos in Periodically Perturbed Monopole + Quadrupole Like Potentials
The motion of a particle that suffers the influence of simple inner (outer) periodic perturbations when it evolves around a center of attraction modeled by an inverse square law plus a quadrupole-like term is studied. The equations of motion are used to reduce the Melnikov method to the study of simple graphics.
