AVERAGE RESONANCE CAPTURE IN COBALT AND MANGANESE USING BORON-10 FILTER TECHNIQUE

Abstract

<p>The high energy gamma rays from the radiative capture of B¹⁰ filtered neutrons in Mn⁵⁵ and Co⁵⁹ were measured and analyzed in terms of statistical and direct capture model of nuclear reactions. A high resolution NaI(T1)-Ge(Li) pair spectrometer was used to detect the gamma rays. Correlations between (n,Υ) and (d,p) intensities were determined for these nuclei. The distributions of the reduced intensities were also studied and compared with the predictions of the statistical model. Finally an attempt was made to determine a direct capture component in the Co⁶⁰ ground state partial cross-section. It was found that the ground state data could be explained with the resonance amplitudes alone. The following amplitudes were deduced: [equation removed]</p>
