含有超重原子的分子可以被人工创造出来，作为研究超重态破坏现象的灵敏探针。在这里，我们提供了详细的理论研究的相关量的电子电偶极矩（eEDM）和核-电子标量-赝标量相互作用的双原子分子中含有超重的lawrencium核。宇称和时间（或等价地，CP）反转违反性质的敏感性进行了研究，为不同的中性和离子分子。发现这些系统中的有效电场比正在进行eEDM实验的其他已知分子大约3-4倍。同样，这些超重分子表现出超过3倍的增强破坏标量-赝标核-电子相互作用。我们使用Woods-Saxon核模型的初步分析也表明，这些结果是敏感的扩散表面的相互作用内的Lr核。我们还简要地评论了一些实验方面讨论这些系统的生产。
Molecules containing superheavy atoms can be artificially created to serve as sensitive probes to study symmetry-violating phenomena. Here, we provide detailed theoretical studies of quantities relevant to the electron electric dipole moment (eEDM) and nucleus-electron scalar-pseudoscalar interactions in diatomic molecules containing superheavy lawrencium nuclei. The sensitivity to parity and time (or, equivalently,CP) reversal violating properties is studied for different neutral and ionic molecules. The effective electric fields in these systems are found to be about 3–4 times larger than other known molecules on which eEDM experiments are being performed. Similarly, these superheavy molecules exhibit an enhancement of more than 3 times for-violating scalar-pseudoscalar nucleus-electron interactions. Our preliminary analysis using the Woods-Saxon nuclear model also demonstrates that these results are sensitive to the diffuse surface interactions inside the Lr nucleus. We also briefly comment on some experimental aspects by discussing the production of these systems.
