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

Complete fusion (CF) and incomplete fusion (ICF) reactions were studied for the cases of the loosely bound ⁶He and ⁶Li projectiles bombarding ¹⁶⁶Er and ¹⁶⁵Ho 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 ¹⁶⁵Ho (⁶Li, ⁵n) ¹⁶⁶Yb and ¹⁶⁶Er(⁶He, ⁶n) ¹⁶⁶Yb as well as ICF ¹⁶⁵Ho (⁶Li, α3n) ¹⁶⁴Er and ¹⁶⁶Er(⁶He, α4n) ¹⁶⁴Er 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.
