Excitation functions of ⁶Li incomplete fusion reactions with Pt nuclei

Experimentally determined excitation functions of the transfer reactions producing 194–199Au and 197m Hg isotopes during the interaction of 6Li with Pt nuclei are presented. An analysis of the experimental data as compared to EMPIRE-2.18 model calculations and experimental results on the d + natPt and α + natPt reactions allow determination of the interaction channels of d- and α-clusters in 6Li with the target nucleus. The results from model calculations of the reaction cross sections appear considerably lower than the experimental data. This discrepancy in describing the reactions with weakly bound nuclei is probably associated with the incomplete consideration of various interaction channels in the EMPERE-2.18 software. It is clear that a complete understanding of the interaction pattern in these processes requires consideration of the direct channels of 6Li nucleus cluster transfer during 6Li breakup near the Coulomb barrier.
