  12. CONCLUSIONS Thank you! Analysis of deuteron induced reactions should consider BREAKUP & STRIPPING & PICK-UP & PE & CN MECHANISMS • DIRECT INTERACTIONS (DI) effects to d interactions: BREAKUP: DOMINANT for heavy targets at Ed~VC(surrogate) BREAKUP ENHANCEMENT of activation c.s. (d,t) pick-up : exclusive contribution to low-energyEF side (d,p) stripping : dominant role in (d,p) reactions • PE & EVAPORATION cross sections corrected for initial d-flux leakage towards DIRECT INTERACTIONS ???Padé APPROXIMATIONS as long as there are Available Nuclear Reactions Codes and Powerful Computers ??? 15th Varenna Conference on Nuclear Reactions Mechanisms, June 11-15, 2018
