本文研究了室温下Ca+库仑晶体与极性分子nh3和nd3之间的激光诱导反应。利用Ca+库仑晶体荧光图像的大小随时间的变化，测定了Ca+*(3d 2 D 3/ 2,4p 2 P 1/2)+ nh3 （ND 3）→产物的反应速率。结果表明，共感冷却分子离子与慢速nh3 （nd3）分子之间的反应速率测量可以用Ca+库仑晶体作为冷却剂进行。
We have studied laser-induced reactions between a Ca+ Coulomb crystal and the polar molecules of NH 3 and ND 3 at room temperature. The reaction rates of Ca+*(3d 2 D 3/2, 4p 2 P 1/2)+ NH 3 (ND 3)→ products have been determined from time variation of the size of fluorescence images of Ca+ Coulomb crystals. The results show that the reaction rates are very slow, and therefore the reaction-rate measurements between sympathetically cooled molecular ions and slow NH 3 (ND 3) molecules can be performed using a Ca+ Coulomb crystal as coolant.
