Systematics of mean resonance spacing and average radiative width from random forest regression

Abstract The interaction of a nucleus with photons plays key role in understanding competition nuclear reactions. photon strength function (PSF) gives the average response to an electromagnetic probe. In this study, estimation is performed mean resonance spacing and radiative width 22 nuclei range A = 46 – 90. calculations for analysis are done TALYS. addition, machine-learning driven approach determining experimentally obtained model parameters from neutron/proton mass number given. reasonable agreement within uncertainties achieved between dependent calculations, using TALYS, results random forest regression.
