Nevertheless, current spectroscopic assessments of He-like ions, such as Li + and Be 2+ , encounter constraints in precision owing to the formidable Doppler effect inherent in ion beam experiments. Addressing this challenge, we propose a methodology of employing ion trap confinement and sympathetic cooling techniques to mitigate the impact of the Doppler effect on 9 Be 2+ ions. Through molecular dynamics simulations, we investigated the influence of different ion systems on the temperature and efficiency of sympathetic cooling for 9 Be 2+ ions. Our findings offer valuable insights for future endeavors aimed at conducting high-precision spectroscopic measurements involving trapped and cooled 9 Be 2+ ions or other He-like ions. few-body systems 9Be2+ ions precision spectroscopy sympathetic cooling Full Text Additional Declarations No competing interests reported.
