“…3. The N2~/N2p ratio measured recently at 800 keV by Clouvas et al [12] seems to be in agreement with our results assuming a small in-crease of the NzJN2p value at higher energies, as suggested by the high energy trend of the Gabrielse's results. They are not in agreement with the other previous measurements in the same energy range.…”

Ratios N2s/l~3. of 2s to 3p populations in hydrogen atoms formed by the passage of protons through carbon foils have been measured using the beam-foil-laser excitation method reported very recently. No dependence of Nz~/N;p on the incident proton energy Ep, in the 100-300 keV energy range analysed, is observed. From the ratio N3p/Nzp of 3 p to 2p beam-foil populations in hydrogen reported previously (N3 piN2 p independent of Ep for Ep> 100 keV) and the ratios N2JN3p measured in the present work, a mean value of N2s/N2p equal to 0.61 ___ 0.04 is deduced. These results are compared with available experimental data.

“…At first, the fitting procedure is ap- Figure 4 shows the observed difference intensity with dots and their least-square-fit by a curve. Then adopting this pair of values of a(spO), the observed intensity I(+ F, t) was fitted to (5). The reason why we adopt the intensity I( + F, t) is that the observed modulation is clearly larger In Fig.…”

“…They have clearly showed the role of the external electric field. The Ly-e radiation of hydrogen atom was further studied by Gabrielse [4], and recently by Clouvas et al [5]. This method has been applied by Denis et al [6] to 4He II 468.6 nm emission to clarify the excitation mechanism responsible for the formation of excited states.…”

Abstract. The Stark beats of Lyman-e emission due to n = i -2 transition of hydrogen atom have been studied by the beam-foil method. After passage through a thin carbon foil, the static electric field of 500 V/cm was applied to the beam in the direction either parallel to or anti-parallel to the the beam velocity. The linearly polarized emission was measured by using a toroidal mirror at a Brewster's angle reflection. When the direction of the applied electric field is reversed, an appreciable phase shift was observed. The analysis of the data leads to the complete determination of the density matrix of the H(n = 2) atoms at the time of their production.
