[en] Experimentally measured excitation functions produced via different emission channels have been compared with theoretical predictions based on statistical model code PACE-4 and interpreted in terms of CF and/or ICF. EFs for several residues ¹⁸⁸Au, ¹⁸⁹Pt, ¹⁸⁸Pt, ¹⁸⁷Ir, ¹⁸⁵Ir and ¹⁸⁴Ir etc. have been measured for the system ¹⁸O + ¹⁷⁵Lu using the recoil catcher activation technique at energies ranging from 4-6 MeV/nucleon. Theoretical model code PACE-4 gives only the CF cross section and does not take into account the ICF processes. This code is based on the Hauser- Feshbach theory of compound nucleus (CN) decay and uses statistical approach of CN deexcitation
