Investigation of the γ-ray strength function in 51V by means of the average resonance method

Abstract

A three-crystal pair spectrometer has been used to study the 50Ti(p, γ) 51V reaction for E p = 2.1–2.5MeV and2.6–3.1MeV The γ-ray spectra were measured throughout the proton energy interval in steps of about 15 keV. These spectra were added to get only one averaged spectrum. The intensities of high-energy γ-transitions populating the low-excited states of 51V have been determined. The intensities of the γ-rays to final states with known J π values were tested against theoretical calculations based on the Hauser-Feshbach theory with good results. The γ-ray strength function for energies lower than 11 MeV has been evaluated from the measured average intensities of primary γ-rays.
