dc.description.abstract The 48Ti(p, gamma)49V reaction was studied in the energy range Ep = 2.0--2.8 MeV. This research was performed at the High Resolution Laboratory at Triangle Universities Nuclear Laboratory. Capture spectra were obtained for 27 compound nuclear resonances whose resonance parameters (energy, spin, parity, and particle widths) had been determined in earlier experiments. The gamma rays were measured with a Compton-suppressed HPGe detector. A total of ten 1/2+ resonances, nine 1/2- resonances and eight 3/2 - resonances were studied. The primary motivation for these measurements was to provide a data set suitable for testing the applicability of conventional statistical models in this mass region. A secondary motivation was to evaluate the 'low level population' method (which works very well in heavier nuclei) in this mass region. The relative populations of 10 of the first 12 excited states of 49V were determined (the relative populations of two of the low-lying states could not be obtained due to gamma-ray resolution limitations). The average relative populations were similar for the three types of resonances. The experimental relative populations were compared with calculations performed with the statistical model code DICEBOX. Results for a variety of radiative strength function models yielded qualitatively similar results. These simulations agree only qualitatively with the experimental relative populations. Although the simulations suggest that the low level population method may work in this nuclide, the experimental results are at best ambiguous. Thus the statistical approach provides a reasonable qualitative description (but not a quantitative description) of the relative population of low-lying states in 49V. en_US
