Study of complete and incomplete fusion for loosely bound projectiles 6 He and 6 Li on 165 Ho and 166 Er targets

Complete fusion (CF) and incomplete fusion (ICF) reactions were studied for the cases of the loosely bound 6 He and 6 Li projectiles bombarding 166 Er and 165 Ho targets at energy of about 10 MeV/nucleon. Experiments were carried out to test an approach exploiting the measured intensities of γ rays emitted at the transitions between the yrast-band levels of reaction products formed after the termination of neutron evaporation. Partial waves feeding the CF reactions 165 Ho ( 6 Li, 5 n ) 166 Yb and 166 Er( 6 He, 6 n ) 166 Yb as well as ICF 165 Ho ( 6 Li, α3 n ) 164 Er and 166 Er( 6 He, α4 n ) 164 Er reaction channels were revealed from the obtained γ-ray data. The method of exit channel identification via the triple coincidence (γ1-γ2-light charged particle) was employed for these reactions study.
