dc.description.abstractENGLISH ABSTRACT: The interaction of a nucleus with γ-rays plays a key role in a theoretical understanding of competi- tion in and components of nuclear reactions. The photon strength function (PSF) gives the average response of a nucleus to an electromagnetic probe. In this thesis, a study is done of the nuclear level density (NLD) and PSF of 22 isotopes in the range (A = 46 − 90) arising from a (p,γ) reac- tion. The calculations for this analysis are done in TALYS. In addition, a machine-learning driven approach for determining experimentally obtained model parameters from the neutron/proton and mass number is given.en_ZA
dc.description.abstractAFRIKAANSE OPSOMMING: Die interaksie van ’n kern met γ-strale speel ’n sleutelrol in ’n teoretiese begrip van mededinging in en komponente van kernreaksies. Die fotonsterktefunksie (PSF) gee die gemiddelde reaksie van ’n kern op elektromagnetiese ondersoek. In hierdie tesis, word ’n studie gedoen van die kernvlakdigth- eid (NLD) en PSF van 22 isotope in die reeks (A = 46 − 90) wat voortspruit uit ’n (p,γ) reaksie. Die berekeninge vir hierdie analise word in TALYS gedoen. Daarbenewens word ’n masjienleer- gedrewe benadering gegee vir die bepaling van eksperimenteel verkryde modelparameters vanaf die neutron/proton en massagetal.af_ZA
