Abstract

As a function of the barrier height, center-of-mass energy, Coulomb interaction parameter and [Formula: see text], a new empirical formula for the astronomical [Formula: see text]-factor has been proposed. Around 14 fusion reactions using [Formula: see text]Ti as projectiles were taken into consideration for various targets, producing compound nuclei with atomic and mass number ranges of [Formula: see text] and [Formula: see text], respectively. The geometric factor, Gamow–Sommerfield factor and empirical [Formula: see text]-factor formulas have been used to determine the fusion cross-sections. Compared to Wong’s formula, this study shows a better agreement with the available experiments except for the [Formula: see text] and [Formula: see text] fusion reactions. When employed to correlate with the experimental data on titanium-induced fusion reactions, this study yields a lower standard deviation value than Wong’s formula except for the fusion reactions leading to the formation of compound nuclei [Formula: see text]Hf and [Formula: see text]Th.

44≤Z≤104范围内ti诱导熔合截面的研究
作为势垒高度、质心能量、库仑相互作用参数和[公式:见文]的函数,提出了一个新的天文[公式:见文]因子的经验公式。以[公式:见文]Ti为弹丸,对不同的目标进行了大约14次核聚变反应,产生了原子和质量数分别为[公式:见文]和[公式:见文]的复合原子核。采用几何因子、Gamow-Sommerfield因子和经验因子公式来确定熔合截面。与Wong的公式相比,除了[公式:见文]和[公式:见文]的聚变反应外,本研究与现有的实验结果吻合得更好。当与钛诱导聚变反应的实验数据相关联时,除了导致形成复合核的聚变反应[公式:见文]Hf和[公式:见文]Th外,本研究得到的标准差值低于Wong公式。
