CROSS-SECTION OF 90.6 keV γ-RAY GENERATION FOR THE 48Ti(p,γ)49V REACTION OVER THE PROTON ENERGY RANGE 0.95-2.8 MeV

Abstract

The differential cross-section of 48Ti(p,γ)49V reaction was measured with 90.6 keV γ-rays (the transition from the first excited state of 49V to the ground state) and 900 detection angle. An isotope titanium target of 97.8% 48Ti content and thickness 3.6·1018 at.Ti/cm2 was used. Such a thickness value provided averaging of the cross-section over several contiguous resonances, improving the accuracy of cross-section measurements. There is general agreement of maxima and minima in the measured excitation function with analogous reference data for the excitation function measurements in relative units. It was shown that for proton energies up to 2.8 MeV the main channel of the 48Ti(p,γ)49V reaction is 90.6 keV γ-ray emission, and this channel can offer the greatest sensitivity for titanium analysis by the PIGE technique.
