给出了用光子计数技术测得的Cs2分子在[-5.02，-2.45 cm-1]到(6S1/2+6P3/2)离解极限范围内的长程分子1g态的光缔合光谱数据，得到了18个新的高振动能级.将实验数据与改进的LeRoy-Bernstein(LRB)公式进行拟合，得到了高精度的长程分子系数c3，并通过对拟合残差的分析，论证了改进的LRB公式提高c3系数精度的必要性。
The photoassociation spectroscopic data of the long-range molecular 1g state of Cs 2 in the asymptotic range red detuned [-5.02, -2.45 cm -1 ] to the (6S 1/2 +6P 3/2 ) dissociation limit detected using photon counting technique are presented and 18 new high-lying vibrational energy levels are obtained. Fitting experimental data to the improved LeRoy–Bernstein (LRB) formula, we have obtained the long-range molecular coefficient c 3 with a high precision and also demonstrated the necessity of the improved LRB formula for more precise c 3 coefficient by analyzing the residual from fitting procedure.
