Evidence for large angular momentum window associated with incomplete fusion reactions

Mean values and variances of the angular momentum window of incomplete fusion reactions induced by 16O on 116-124Sn targets at 90, 100 and 125 MeV have been measured. The γ multiplicity technique has been used to extract these quantities for each reaction channel identified by discrete γ lines. Incomplete fusion seems to appear in about the same angular momentum window than complete fusion. This is confirmed by the observation of α2p4n and 2α4n channels appearing at low angular momentum in the 125 MeV reaction. (orig.)
