论文摘要
最近，由于新实验性的隔离/CRIS技术在赖氏镭分子的光谱方面的成功应用，对放射性化合物光谱的新兴浪潮已经提高。这为搜索与``新物理学''相关的效果的搜索打开了巨大的前景，这指向物理定律与标准粒子标准模型建立的效果相对于物理定律的偏差。捕获工作分子的能力，它们的激光冷却性和共磁性计分子状态以及分子中具有不同核多极矩的分子元素的各种可访问的核同位素的能力，可以为搜索这种效果的实验提供可观的优势。含有RA核的激光可冷却多原子离子应符合上述标准，在本文中，我们正在考虑许多前瞻性分子离子并计算其电子结构和分子特性。
Recently a new wave of interest to spectroscopy of radioactive compounds has raised due to successful applications of the new experimental ISOL/CRIS technique to optical spectroscopy of radium monofluoride molecules. This opens great prospects to searches of the effects connected with ``new physics'' which point on deviations of the physical laws from those established by Standard Model of elementary particles. Considerable advantages in experiments for search for such effects would be provided by the abilities to trap the working molecules, their laser-coolability and presence of co-magnitometer molecular states and also a variety of accessible nuclear isotopes of the elements in the molecule with different nuclear multipole moments. Laser-coolable polyatomic molecular ions containing Ra nuclei shall meet the above criteria and in the present article we are considering a number of prospective molecular ions and calculating their electronic structure and molecular properties.
