The effect of statistical fluctuations on the measurement of the total energy and multiplicity of γ rays following deep-inelastic reactions

We discuss the effect of statistical fluctuations on the first and second moments of both the intrinsic rotational energy and the sum of spin magnitudes in deep-inelastic fragments, as extracted from measurements of the total γ-ray energy and the γ-ray multiplicity, respectively. The calculations were done in the framework of a model that considers the thermal excitation of rotational modes in the intermediate dinuclear complex, accounting exactly for the correlations between the angular momenta generated in both nuclei.
