Production of Lyman-αradiation in collisions of protons and hydrogen atoms

Compact homogeneous manifolds with integrable invariant distributions, and scalar curvature

“…The agreement with the measurements of Detleffsen et al [1] is very good except for 2p and 3p excitations at 40 keV-the lowest energy considered in that experiment. In contrast, figure 2(b) shows that our results merge smoothly into the 2p low energy data reported by Kondow et al [17] (this is also the case for early low energy data not shown in the figure [18,19]). Agreement with previous theoretical calculations for 2p excitation [3,10,15,20,21] and np excitation with n > 2 [10,15] is good in the whole energy range investigated here.…”

Electron excitation of hydrogen atom by ions impact in the energy range 20–1000 keV/amu

“…This work supports the existence of distortion effect in electron excitation to bound states of the target as predicted by Bugacov et al [25].Tong et al [26] studied the excitation and charge (including resonant charge transfer) transfer processes of H + and H collisions in a wide range of collision energies by solving the time-dependent Schrodinger equation which is solved by the split-operator method with a generalized pseudospectral (non uniform grid) method. The calculated impact excitation and charge transfer cross sections are in reasonable agreement with the available experimental measurements, Tong et al [26], Morgan et al [27], Chong and Fite [28], Stebbings et al [29], Kondow et al [30]. Electron excitation to H atom from n = 2 to n = 3 states in 1-300 keV/amu He 2+ + H collisions is studied by Fritsch et al [31] within the semiclassical close-coupling method with AO basis sets.…”

“…For 2p excitations, our BCCIS results in Figure 1(b) are compared with the theoretical results of Schultz et al [14], Errea et al [20], Shakeshaft [39] and Tong et al [26]. For comparison experimental results of Stebbings et al [29], Morgan et al [27], Kondow et al [30], Detleffsen et al [29] in the low energy region (10-20 keV) departure from the present results is quite sharp. Results of Detleffset et al [23] overestimate our results in the whole energy region.…”

Recent advances in the chemistry of Rh carbenoids: multicomponent reactions of diazocarbonyl compounds

“…These measurements were subsequently revised by Young et al[71] in measurements spanning the range 0.5-30 keV.More recently Morgan et al[72] and Kondow et al[73] Fig. 9.…”
