摘要
用多步激发的方法,将Sr原子从基态5s^2经价态4α^(-2)激发至(4d_(3/2)np,n_f)J=1和(4d_(5/2)np,nf)J=1自电离系列,观察其在外电场0～5kV/cm内的光谱.对所观察到的n=12,13,14附近的斯塔克谱图进行了分析与讨论.
By using the multi-step excitation technique, Sr atoms are excited from ground state 5S2 to (4d3/2np, nf)J=1 and (4d5/2np, nf)J=1 autoionizing states via valence state 4d23P0. Their Stark spectra near n = 12, 13, 14 in an electric field of 0-5kV/cm are observed and discussed.
