The DIAMANT-AFRODITE combination has been used to investigate incomplete fusions reactions via the {sup 13}C+{sup 170}Er entrance channel. The intensity of {sup 176}Hf (populated via the {alpha} 3n exit channel) is {approx}8% of {sup 178}W (populated via 5n evaporation) which is {approx}8 times stronger than that expected from complete fusion. Moreover, 2{alpha}xn exit channels leading to Yb nuclei are observed with intensities that are {approx}30-to-40% of {sup 176}Hf, for which no yield is expected from complete fusion. A comparison of the intensities from the two-{alpha}- and one-{alpha}-gated data is consistent with fragmentation of the {sup 13}C beam into ({alpha}-{alpha}-{alpha}-n) which suggests that the population of Yb nuclei results from fusion (or ''massive transfer'') of one the break-up {alpha}-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 {sup 32}S.
