M x-ray production cross sections of heavy elements for low and high proton energy
Abstract
The semi-empirical cross sections have been deduced by individual fittings of the updated experimental data (from 1980 till 2009) and normalized to their corresponding theoretical values (ECPSSR model) for elements with 72≤Z≤90 by protons energies varying from 0.1 to 4.0 MeV. Also, based on the individual fittings of the elements and the remarkable deviation of the experimental data from the ECPSSR values for low proton energy, we attempt to deduce another semi-empirical cross sections by introducing the low-high proton energy procedure which separates the fitting of the semi-empirical cross sections for low proton energy from those for high proton energy. Our results are presented for selected heavy elements. Finally, a comparison is made between our results and the experiment.
