Electric-field dependence ofE1 transitions between highly excited hydrogen Stark sublevels

“…At zero field, the lowest sublevel in the n = 10 manifold is 10 zPi~z, and it evolves into the (10,0,9,0) sublevel at high electric field. Either this sublevel or the highest n = 10 sublevel, (10,9,0,0) in high field, were the lower states in the transitions studied here Similarly, in the n = 30 manifold, the lowest sublevel evolves from 30 Piy2 into (30,0,29,0). The next higher sublevel at zero field is 30 2Si~q, which is displaced upward by the Lamb shift.…”

“…For the chosen laser line, each laser was stabilized to within a few MHz of the center of its gain curve with use of the optogalvanic effect [23]. The first laser excited atoms from the substate (7,0,6,0) to (10,0,9,0) in the field Fi = 29.5 kV/cm. There were no collisionally populated (10,0,9,0) atoms (or any other n = 10 atoms) at this point because of the Fq quenching field.…”

There were no collisionally populated (10,0,9,0) atoms (or any other n = 10 atoms) at this point because of the Fq quenching field. The field Fz 400 V/cm was used to preserve quantization after Fi.…”

“…The early work in discharge or "canal ray" tubes was complicated by collisional efFects and the nonisotropic plasma environment. Intensity measurements on the Lyman (n to p) [10] and Balmer (also cs to p) [11 -13] series at fields of 12 to 250 kV/cm, reviewed in Ryde [13] and in Condon and Shortley [14], did obtain relative intensities within a few percent of theory. More recently, Ng, Yao, and Nayfeh [15] have used laser and thermal atomic beam techniques to measure intensities of transitions from n = 2 to various n = 15 -18 sublevels at F = 16.7 kV/cm.…”

“…This evolves into añ mL,~= I sublevel, (30,0,28,1), that is excited negligibly from (10,0,9,0) when the laser radiation is polarized parallel to the field. The transitions of primary interest are thus (a) from (10,0,9,0) to (30,0,29,0) and (b) from…”
