The experimental verification of compound nucleus theory has successfully been performed for light ion induced reactions using proton and α-particle beams on different targets. However, such studies using the heavy ion beams are scarce due to the complex nature of heavy ion interaction process. The present work is an attempt to validate the Bohr's independent hypothesis using heavy ion beam of ¹⁸O beam on ¹⁵⁹Tb targets and ¹²C on ¹⁶⁵Ho targets, forming the same compound nucleus ¹⁷⁷Ta. A channel wise analysis of cross section data for evaporation residues produced in ¹⁸O+¹⁵⁹Tb and ¹²C+¹⁶⁵Ho systems has been performed within the framework of statistical model code PACE4 and found to reasonably agree with the experimental data. Further, a comparison of reaction cross section data for the same evaporation residues produced in the two different systems has been found to follow Bohr's compound nucleus hypothesis at relatively higher excitation energies. However, at relatively lower excitation energies, a significant deviation in the measured cross section data of the same residues in the above mentioned systems have been observed and is attributed to the discrepancies in angular momentum values. Such discrepancies are well explained on the basis of input angular momentum involved in the reactions.

已成功对不同目标上使用质子和α粒子束的轻离子诱导反应进行了复合核理论的实验验证。然而，由于重离子相互作用过程的复杂性，使用重离子束的此类研究很少。^{目前的工作是尝试使用18} O 束重离子束照射¹⁵⁹ Tb 靶材和¹² C 照射¹⁶⁵ Ho 靶材，形成相同的复合核¹⁷⁷ Ta，来验证玻尔的独立假设。^{在统计模型代码 PACE4 的框架内，对18} O+ ¹⁵⁹ Tb 和¹² C+ ¹⁶⁵ Ho 系统中产生的蒸发残留物的横截面数据进行了通道方式分析，发现与实验数据相当一致。此外，对两个不同系统中产生的相同蒸发残留物的反应截面数据的比较发现，在相对较高的激发能下遵循玻尔复合核假说。然而，在相对较低的激发能量下，观察到上述系统中相同残基的测量横截面数据存在显着偏差，这归因于角动量值的差异。这种差异可以根据反应中涉及的输入角动量得到很好的解释。
