Aiming to probe incomplete fusion dynamics in 16O + 169Tm system, spin-distributions of various reaction products populated via xn-, α/2αxn-channels have been measured at E≈5.6MeV/nucleon. Prompt γ-rays coincidence with fast charged particles (Z=1,2) recorded achieve the information about involved processes on basis their experimentally observed spin-populations during de-excitation. The for direct-α-emitting channels (associated fusion) found be distinctly different than that fusion–evaporation (complete channels. mean value driving input angular momenta associated direct-α/2αxn-channels higher xn/αxn-channels, and increases direct-α-multiplicity forward cone. Experimentally measured, normalized production yields xn/αxn-channels good agreement predictions theoretical model code PACE4. Further, order understand feeding probability both complete products, an attempt has made generate intensity profiles from spin-distribution data. It are strongly fed over a broad spin range, while less and/or population lower states hindered.
