Summary

Single neutron transfer reactions on ¹⁹⁷Au induced by ¹²C and ¹⁶O at near Coulomb barrier energies have been studied using radiochemical and off-line gamma-ray spectrometric techniques. High spin yield fraction (HSF = σ_m/(σ_m+σ_g)) for ^196m,gAu and formation cross section ratio (σ₁₉₈/σ₁₉₆) of ¹⁹⁸Au and ¹⁹⁶Au have been determined for both ¹⁹⁷Au+¹²C and ¹⁹⁷Au+¹⁶O reactions at different excitation energies near the Coulomb barrier. The HSF of ^196m,gAu and σ₁₉₈/σ₁₉₆ values in both reactions are seen to sharply increase with increasing excitation energy near the Coulomb barrier and then slowly increase reaching a constant value at high projectile energy. These observations have been analyzed in terms of nuclear structural and kinematic parameters. A comparison the effects of Coulomb excitation and nucleon transfer process during heavy-ion interactions indicates a predominant effect of the latter process in the background of the Coulomb excitation. Observed reaction systematics seem to follow the quasi-elastic transfer process.
