Аннотация:

The study of nuclear statistical properties is of importance not only in nuclear waste transmutation [1] and nuclear fuel cycles [2] but also in nuclear structure and nuclear astrophysics studies [3]. These statistical properties — the nuclear level density (NLD), which describes the number of available energy levels in a nucleus for a given excitation energy, and the photon strength function (γSF), which is the electromagnetic decay probability for a nucleus to either emit or absorb a gammaray, are critical ingredients into calculations of neutron capture cross sections and astrophysical reaction rates.
In this presentation, measurements of nuclear level densities and photon strength functions performed at iThemba LABS and their applications will be discussed.
