Session 13: Nuclear Structure, Reactions and Dynamics
- Edoardo G. Lanza ()
Neutron-proton pairing is the only pairing that can occur in the T=0 and the T=1 isospin channels. T=1 particle-like pairing (n-n or p-p) has been extensively studied unlike T=0 neutron-proton pairing. The over-binding of N=Z nuclei could be one of its manifestation.
Neutron-proton pairing can be studied by spectroscopy as in ref.[1].We have here studied it through transfer reactions in...
The level density of 2+ states in 208Pb and 120Sn nuclei have been extracted in the energy region of the isoscalar giant quadrupole resonance (ISGQR) from a fluctuation analysis of high-energy-resolution (p,p’) data taken at incident energies of 200 MeV at the K600 magnetic spectrometer of iThemba LABS, South Africa. The shape of the background was determined from the discrete wavelet...
Background: In highly deformed nuclei, there is a noticeable coupling of the Isoscalar Giant Monopole Resonance (ISGMR) and the $K = 0$ component of the Isoscalar Giant Quadrupole Resonance (ISGQR), which results in a double peak structure of the isoscalar monopole (IS0) strength (a narrow low-energy deformation-induced peak and a main broad ISGMR part). The energy of the narrow low-lying IS0...
The investigation of compressional-mode giant resonances, specifically the isoscalar giant monopole resonance (GMR), continues to captivate the interest of nuclear physicists. This research is centered on the meticulous analysis of isoscalar monopole resonances within the 112-124Sn isotopic mass chain, aiming to glean profound insights into nuclear matter compressibility. The lingering...
The cross sections of proton-nucleus scattering at eneries from 200 to 1000 MeV are calculated within the microscopic model of folding optical potential. Such potential is determined by the amplitude of scattering of an incident proton on the bound nuclear nucleon which itself depends on three parameters, namely the total nucleon-nucleon scattering cross section, the ratio of real to imaginary...
