摘要
This paper provides a comprehensive analysis of all stages of the heavy-ion fusion evaporation reaction,aiming to enhance the understanding of the entire process and identify the influencing factors in calculating the evaporation residue cross-section.By focusing on the synthesis of superheavy nuclei with Z=114,we discuss the capture cross-section,fusion probability,and survival probability of the ^(48)Ca+^(244)Pu reaction and compare them with those of the 40Ar+248Cm reaction.Moreover,a systematic study examined the evaporation residue cross-sections for the synthesis of superheavy nuclei with Z=112-116 using ^(40)Ar as the projectile nucleus.The results indicate that utilizing ^(40)Ar as the projectile nucleus for synthesizing isotopes with Z=114 offers advantages such as lower incident energy and reduced experimental costs.Furthermore,using ^(40)Ar as the projectile nucleus enables the synthesis of a new key isotope,285115,thereby facilitating its identification.
