摘要

在逆运动学中,我们探索了库仑裂变截面和时间尺度。研究了238U、132Xe和208Pb等较重射弹对16O、26Mg、27Al、32S、35Cl、40,48Ca、45Sc、48,50Ti、56,58Fe、64Ni、89Y、30Si和65Zn等较轻目标的作用。光裂变截面和入射到靶核上的等效光子数是截面评估中的重要参数。预期的横截面随着靶核原子序数的增加而增加。我们还探索了不同跃迁水平下射弹核的时间尺度。估计的时间尺度与可用的实验值非常一致,实验值在皮秒量级。此外,我们还预测了从19/2开始处于过渡态的165Ho原子核的时间尺度+→15/2+至29/2+→25/2+,其实验时间尺度在文献中不可用。因此,库仑裂变是严重阻碍复合核形成的原因之一。特别是时间尺度的预测将有助于理解各种能级的结构。

Investigations on Coulomb fission time scales and cross sections in inverse kinematics

In inverse kinematics, we explored Coulomb fission cross-sections and time scales. Heavier projectiles such as 238U, 132Xe, and 208Pb on lighter targets such as 16O 26Mg, 27Al, 32S, 35Cl, 40,48Ca, 45Sc, 48,50Ti, 56,58Fe, 64Ni, 89Y, 30Si and 65Zn were looked into. The photofission cross-sections and the number of equivalent photons impinge on the target nuclei are important parameters in cross-section assessment. The anticipated cross-sections increases with increase in atomic number of target nuclei. We also explored the time scale of projectile nuclei at various transition levels. The estimated time scales accord well with the available experimental value, which is in the order of picoseconds. In addition, we predicted time scales of 165Ho nuclei in the transition state from 19/2+15/2+ to 29/2+25/2+ for which experimental time scales are not available in literature. As a result, Coulomb fission is one of the causes that has severely hampered in the formation of compound nuclei. Prediction of time scales, in particular, would aid in understanding the structure of various energy levels.
