摘要
In this work, we delved into the intriguing realm of nuclear physics by investigating fusion reactions initiated by 70Zn projectiles colliding with various stable isotopes of thorium nuclei, including Th-227-232,Th-234. Our primary objective was the synthesis of the superheavy element Z=120. To achieve this, we employed an advanced statistical model to evaluate the evaporation residue cross-sections. Remarkably, we observed that the fusion reaction between Zn-70 and 231Th exhibited the highest evaporation residue cross-sections, reaching a peak value. Furthermore, the 3n channel within this fusion reaction yielded substantially larger evaporation cross-sections, with a notable value of 0.89 picobarns. The predicted cross-sections fall within the measurable range, making them highly valuable for experimental endeavors aimed at synthesizing the superheavy element Z=120. This research not only contributes to our understanding of nuclear reactions but also holds promise for expanding our knowledge of the heaviest elements in the periodic table, potentially opening new frontiers in nuclear science.
