Motivation
The study of breakup-fusion mainly focuses on weakly-bound projectiles with breakup thresholds 1.45--2.45MeV. However, 10B also has low α-separation energy (4.5MeV), suggesting it may undergo breakup and significantly impact fusion mechanisms at low energies. Measurements from 10,11B+159Tb/209Bi showed complete fusion suppression of ~15% for 10B and 7% for 11B reactions above the barrier. Since the fusion behavior of 10B and its comparison with 11B remains grossly unexplored in medium and light mass nuclei, we aim to measure fusion excitation functions for 10,11B interactions on 89Y, 59Co, 141Pr within 25--70MeV.
