Fusion excitation function and back angle quasi-elastic scattering studies for the ^12,13C+¹⁹⁷Au

Measurements have been carried out using the recoil mass separator HIRA at IUAC for near barrier heavy ion reactions involving the systems ^12,13C+¹⁹⁷Au. The reactions chosen form part of the reactions selected for the study of the fission survivability of hot rotating compound nuclei formed with increasing neutron number so as to cross N=126 shell closure while keeping the number of protons unchanged. The mass asymmetry of the selected reactions is chosen so as to be more than the α_BG to avoid extraneous effects due to contributions from possible non compound processes while studying the fission survivability of hot rotating nuclei near neutron shell closure. This is in contrast with studies reported so far for the shell closure effects across N=126 shell on fission survivability which have their mass asymmetries lesser than the values of the corresponding α_BG
