Session 14: Neutron Physics
- Peane Maleka (iThemba LABS)
There continues to be a growing need for new compact neutron spectrometers, driven mainly by the requirements for dosimetry in hadron therapy, aircraft, spacecraft, future extra-terrestrial bases, and around high energy accelerator facilities. For dosimetry in the upper atmosphere and in space, neutrons in the energy range exceeding 100 MeV need to be measured. Since neutrons are seldom ...
GANIL/SPIRAL2 presently offers unique opportunities in nuclear physics and in many other fields that arise from not only the provision of low-energy stable beams, fragmentation beams, re-accelerated radioactive species, and recently neutron beams but also from the availability of a wide range of state-of-the-art spectrometers and instrumentation. A few examples of recent highlights will be...
Neutron-induced reactions is a unique tool for investigation of the structure of the atomic nuclei. Analysis of the neutron inelastic scattering data as well as information about processes with charged particle emission allows one to estimate shape and radii of nuclei and deduce the reaction mechanism.
The γ-radiation emitted by excited products of neutron-induced reactions carries...
Silicon is one of the important elements used in modern technics. Information about gamma-rays spectrum of silicon can be used in elemental analysis of various objects. The usage of compact D-T neutron generators with an energy of 14.1 MeV makes it possible to create compact portable setups, as well as to implement the tagged neutrons method by detecting the accompanying alpha particle emitted...
The heavy neutron rich nuclei are very important for nuclear physics investigations, for the understanding of astrophysical nucleosynthesis and r-process. In this region is located the closed neutron shell N=126 which is the last so-called “waiting point”. Study of the structural properties of nuclei along the neutron shell N = 126 could also contribute to the present discussion of the...
The isospin asymmetry of neutron-rich nuclei is expected to impact the excitation energy spectra of such nuclei. The resulting exotic excitation modes which may occur are thus considered to be related to the existence of a neutron excess. The soft monopole resonance, simplistically viewed as the compression of dilute neutron matter in the region of the neutron skin, represents a possible...
