The differential excitation functions of the low lying levels for the reactions Mg24 (d, p) Mg25 and Mg26 (d, p.) Mg27 have been measured in steps of 10 KeV in a deuteron energy range 1.3-2.5 MeV and at angles 20°–160y in steps of 20°. Thin isotopic targets (0.45 μ gm/cm2) on Ni backing (0.5 micron) were used. Auto-correlations, angular and group crosscorrelations, and probability distributions were calculated in terms of ERIOSON's theory of statistical fluctuations. The mean coherence width Γ for both reactions was found to be equal to 32 KeV which corresponds to a life time τ = 2.1 × 10−20 sec. of the compound nucleus formation.
