标题： Revisiting the electron affinity of selenium

摘要： 硒原子的电子亲和力（EA）之前基于2012年的激光光解显微镜（LPM）测量结果确定为16,297.276(9) cm⁻¹，但这一值与早期其他实验结果存在显著偏差，尽管如此，它仍是过去十多年被广泛接受的标准参考值。在这封信中，我们使用慢电子速度图成像（SEVI）方法重新考察了硒的电子亲和力，并揭示了LPM结果存在较大的偏差。对硒的不同同位素以及中性硒原子3P₂ - 3P₁能级分裂的测量进一步验证了我们的SEVI方法的准确性和稳健性。基于这些实验结果，我们推荐修订后的硒电子亲和力值为16,297.78(4) cm⁻¹，该值与先前的激光光解阈值（LPT）实验结果高度一致。 显示英文摘要

摘要： The electron affinity (EA) of atomic selenium, previously established as 16,297.276(9) cm-1 based on the laser photodetachment microscopy (LPM) measurements in 2012, exhibited a significant deviation from other earlier experimental values, yet it remained the accepted reference standard for over a decade. In this letter, we re-examined the EA of Se using the slow-electron velocity-map imaging method and revealed a substantial deviation in the LPM result. Measurements for the different isotopes of Se and the energy-level splitting of the neutral Se atom's 3P2 - 3P1 further verified the accuracy and robustness of our SEVI method. Based on these experimental evidences, we recommended a revised EA(Se) value of 16,297.78(4) cm-1, which is in excellent agreement with the previous laser photodetachment threshold (LPT) experimental results.
