AbstractAbstract
[en] The magnitudes and relative signs of inelastic proton-channel amplitudes have been measured for 71 3/2- resonances in 49V. The measured quantities γ2sub(c), γ2sub(c'), and γsub(c)γsub(c') provide distributions of reduced widths, distribution of the relative sign between reduced width amplitudes, and correlations between reduced widths rho(γ2sub(c),γ2sub(c')) and between amplitudes rho(γsub(c),γsub(c')). A variety of non-statistical effects are observed, including one case in which the effect occurs only in the signs, and not in the magnitudes of the amplitudes. (orig.)

AbstractAbstract
[en] The sample preparation procedure for LSC standardization of a solution of 49VCl5 is described and the time stability of samples is analyzed in four commercial scintillators, HiSafe II, HiSafe III, Ultima-Gold and Insta-Gel Plus. Acceptable stability was obtained in HiSafe III and Ultima-Gold. A self-consistent procedure was developed and successfully applied to the determination of the activity concentration of 49V. The samples were standardized by the CIEMAT/NIST method to a combined uncertainty of 3.4% in the interval of figure of merit 1.2-2.5 (3H equivalent efficiency 40%-20%)

AbstractAbstract
[en] Titanium is an important constituent of several technologically important materials. Its depth profile in the surface regions is desirable for standardizing the manufacturing process and assessment of functionality of materials. The resonance at 1.362 MeV in 48Ti(p,γ)49V reaction (Eγ = 7.9 MeV) has been used for depth profiling Ti in Ti based films. The γ-rays are measured by a bismuth germanate detector. The method has a detection sensitivity of about 6.5 x 1020 at.cm-3 and can provide determinations with a depth resolution of about 25 nm up to a depth of about 800 nm in Si. Selectivity is another important feature of this non-destructive method of depth profiling. (author)

AbstractAbstract
[en] Measurement of the relative sign of inelastic proton-channel amplitudes permits the determination of amplitude correlations. Data were obtained for 45 5/2+ resonances in 49V. Although the reduced widths in each channel followed a Porter-Thomas distribution, large amplitude correlations were observed. The results are compared with the reduced-width--amplitude distribution of Krieger and Porter. This is the first direct test of the Krieger-Porter distribution

AbstractAbstract
[en] Inelastic decay amplitudes from d-wave resonances in 49V were obtained for 80 resonances in the proton energy range 2.2 to 3.1 MeV. With the 3 MV Van de Graaff accelerator and high resolution system at the Triangle Universities Nuclear Laboratory, an overall resolution of 350 eV was obtained. The experiment consisted of measurements of the angular distributions of the inelastically scattered protons and the subsequent deexcitation gamma rays. Forty five resonances were assigned J/sup π/ = 5/2+, while thirty five resonances were assigned 3/2+. The magnitudes of three inelastic decay amplitudes and the relative signs between these three amplitudes were determined. Large amplitude correlations were observed; the data are in the striking disagreement with the extreme statistical model. The present results provide the first explicit test of the multivariate reduced width amplitude distribution of Krieger and Porter; the agreement is excellent. The physical origin of these channel correlations has not yet been explained

AbstractAbstract
[en] Inner bremsstrahlung accompanying electron-capture decay of 49V has been measured with a (4.5 x 5.1)-cm NaI(Tl) scintillation spectrometer in the energy region 180--580 keV. The counts spectrum was unfolded following the procedure of Liden and Starfelt. Results were compared with the (1s+2s)-capture relativistic calculations of Martin and Glauber. At energies higher than 340 keV, the shape of the spectrum agrees with the predictions of the theory. At energies less than 340 keV, experimental values are lower than the theoretical values
