| 摘 要： | 实验获得了Ａｒ＋激光５１４．５ｎｍ线诱导２３Ｎａ３９Ｋ分子产生的Ｄ１∏→Ｘ１∑＋跃迁荧光谱．通过测量激光感生荧光光谱强度随泵浦功率、热管炉温度及缓冲气压变化规律，详细研究了其跃迁机制．用最小二乘法拟合获得２３Ｎａ３９Ｋ分于Ｘ１∑＋态振动常数．理论计算了各跃迁谱支波长值及Ｆｒａｎｃｋ－Ｃｏｎｄｏｎ因子和光谱强度值，与实验观测值符合得相当好，充分表明本文对激光感生荧光光谱的归属以及对各支谱线振、转量子数的赋值是合理的．

| Abstract: | In this paper,we have obtained LIF spectrum of D1 ∏→ X1 ∑+ of NaK induced by 514. 5 um of CW Al+ laser, assigned the spectrum by the known molecular constants, analysed and discussed the emission mechanism of LIF in detail. The vibrational constants of X 1 ∑+ state have been provided by using the least-square fit. The calculated wavelength values are in good agreement with the measured results. We also calculateFranck- Condon factors and intensities of each Q-branch transition. The computed intensities coincide with the observed very well in considering dependence of transition dipole moment Re(r) on r. It proves that the values of vibrational and rotational quantum numbers (v,J) we have determined are reasonable. |
