Abstract

The ⁵¹V(n,d) ⁵⁰Ti reaction has been studied with neutrons of energy of 21.6 MeV. The measurement of the angular distribution of the differential cross section was made with the aid of a spectrometer designed by Dr. McMurray and Prof K. Bharuth - Ram. The spectrometer consists of three multiwire proportional counters followed by a curved plastic scintillator. The proportional counters act as ΔE detectors and the scintillator acts as an energy detector. The ΔE - E method based on the Bethe - Bloch formula was used for particle identification. The spectrometer allows accumulation of data over an angle range of ≥ 70°, has angular resolution (FWHM) ≈ 5° and energy resolution (FWHM) ≈ 0.8 MeV. A review of the optical model and the reaction mechanism is presented. Theoretical DWBA cross sections are performed by using the Distorted Waves code DWUCK4. Spectroscopic factors for transitions to the 0⁺, 2⁺ and (4⁺ , 6⁺ ) states in ⁵⁰Ti have been determined from the comparison of experimental differential cross sections to theoretical DWBA differential cross sections. These have a mean value of 0.42, 0.30 and 0.38 respectively. The spectroscopic factors are compared with the results from (e,e' p) and (d,³He) measurements and shell model calculations.
