用不同邻近势系统研究中子过剩对聚变截面的影响

The systematic study of the influence of neutron excess on the fusion cross sections using different proximity-type potentials

O. N. Ghodsi, R. Gharaei

摘要:

利用不同类型的邻近势,我们研究了50个同位素体系的势垒特性(势垒高度及其位置)和熔合截面的变化趋势,包括C,O,Mg,Si,S,Ca,Ar,Ti和Ni核在复合体系的$1\leq N/Z < 1.6$条件下的各种碰撞。研究结果表明,随着$N/Z$比例的增加,势垒位置的增加和势垒高度的降低均呈线性关系。此外,熔合截面也随该比例的增加而线性增加。

英文摘要:

Using different types of proximity potentials, we have examined the trend of variations of barrier characteristics (barrier height and its position) as well as fusion cross sections for 50 isotopic systems including various collisions of C, O, Mg, Si, S, Ca, Ar, Ti and Ni nuclei with $1\leq N/Z < 1.6$ condition for compound systems. The results of our studies reveal that the relationships between increase of barrier positions and decrease of barrier heights are both linear with increase of $N/Z$ ratio. Moreover, fusion cross sections also enhance linearly with increase of this ratio.
