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

A three-crystal pair spectrometer has been used to study the 50Ti(p,γ)51V reaction for Esub(p)=2.1-2.5 MeV and 2.6-3.1 MeV. The gamma-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 gamma transitions populating the low-excited states of 51V have been determined. The intensities of the gamma rays to final states with known Jsup(π) values were tested against theoretical calculations based on the Hauser-Feshback theory with good results. The gamma-ray strength function for energies lower than 11 MeV has been evaluated from the measured average intensities of primary gamma rays. (author)
