Abstract

It may synthesis transuranium elements with atomic numbers between 92 and 100 in proton-induced reactions or high flux neutron captured by uranium in nuclear rectors. However, it is not possible to synthesize nuclei with atomic numbers greater than 100 in the reactions mentioned above. For the synthesis of heavier nuclei, ion fusion with heavy nuclei can be used. Depending on the type and purpose of the projectile and the amount of energy of the projectile, the fusion process can be performed in three different ranges: cold fusion, hot fusion and superhot fusion. To perform the fusion process, accelerators can be used to accelerate the ions, to overcome the Coulomb repulsion between the projectile and the target to make the fusion process possible. It should be noted that the cost of accelerating ions is very high, so before the synthesis process, it is appropriate to determine the type of projectile and the target and the appropriate kinetic energy for the projectile after leaving the accelerator, according to theoretical work. then should be theoretically identified the synthesis of the produced nucleus's probability to avoid repeated experiments. Here we intend to investigate the possibility of synthesizing some isotopes of nobelium nuclei during the process of fusion of calcium ions with lead nuclei. We must first calculate the barrier against fusion of calcium nuclei with lead by considering the Coulomb potential energy, nuclear potential energy and rotational energy. Then we examine the factors affecting the formation of the composite nucleus. Then, assuming the formation of a composite nucleus, we must examine what channels the nuclei produced decay through, and finally estimate the probability of synthesis of No nuclei according to theoretical concepts. In conclusion, comparing the extracted results with experimental data, we will show that in the framework of the statistical model used, the results of the cross-sectional area of the remaining nucleus for th
