Abstract

The DIAMANT-AFRODITE combination has been used to investigate incomplete fusions reactions via the 13C+170Er entrance channel. The intensity of 176Hf (populated via the α 3n exit channel) is ∼8% of 178W (populated via 5n evaporation) which is ∼8 times stronger than that expected from complete fusion. Moreover, 2αxn exit channels leading to Yb nuclei are observed with intensities that are ∼30-To-40% of 176Hf, for which no yield is expected from complete fusion. A comparison of the intensities from the two-α-and one-α-gated data is consistent with fragmentation of the 13C beam into (α-α-α-n) which suggests that the population of Yb nuclei results from fusion (or "massive transfer") of one the break-up α-particles. A campaign of measurements is scheduled for late 2007 with further investigations planned for 2008, including the continuation of the study of superdeformation in 32S.
