ملخص: Prompt [gamma]-rays emitted during the bombardment of zeolite samples with 1.7 MeV protons are used for the simultaneous quantitative analysis of Al, Mg, Na Si, C and P. Elemental concentrations are determined and a comparison of the resulted unit cell composition of Y-faujasite and MAPO-5 with the given literature data is made. The measured values of the stopping powers of an average energy ranged from 1161 keV to 2645 keV are presented and compared to calculated ones from Bragg's formulae, using simple summing up of constituent element data. A good agreement is obtained.
