“…The first one is very close to the iS resonance at 9.553 eV with width 0.0048 eV. The latest two experiments [10,11] observed resonances at 9.557 and 9.549 eV, with energy resolutions 0.02 and 0.025 eV.…”

An application of the coupled-channels optical method to energy-dependent phenomena, electronhydrogen resonances for n = 1 and 2, is given. The equivalent local approximation is made for the optical potential. The calculation includes nine explicitly coupled channels. The optical potential accounts for the target continuum. The good agreement~ith experiment showers the role played by the optical potential in the coupled-channels calculation. Some additional resonances have been found, PACS number(s): 34.80.8m, 34.80.Dp

“…For the other new resonance at 9.875 eV there is a very weak sign of resonance in the vicinity of this energy in the experiment [11]. It still needs the confirmation of further experiments.…”

“…We have displayed in figure 8 a zoom of the resonance region, close to the H(n = 2) threshold. One may identify three well-known narrow resonances in e − -H system, which are also confirmed experimentally [36][37][38]. One S-wave resonance is visible in e + -H system.…”

“…Table II gives the position and widths of the lowest resonance for each partial wave below the n=2 threshold. These results are compared with those obtained by R-matrix theory [6], complex coordinate rotation calcu-lation [11 -13], Feshbach projection operator formalism [14], a recent hyperspherical calculation [15], and experimental results [16]. The resonant calculations were carried out using a 20 x 20 grid with r~= 64.…”

The Rapid Communications section is intended for the accelerated publication of important new results. Since manuscripts submitted to this section are given priority treatment both in the editorial once and in production, authors should explain in their submittal letter why the work justifies this special handling AR. apid Communication should be no longer than 4 printed pages and must be accompanied by an abstract. Page proofs are sent to authors.A direct numerical solution of the Schrodinger equation for quantum scattering problems is presented. The wave function for each partial wave is expanded in coupled spherical harmonics and the corresponding radial functions are expanded in a local basis set using finite-element analysis, with the appropriate scattering boundary conditions. The method is shown to give very accurate results for elastic phase shifts (S, P, D, and E) and resonance positions for electron-hydrogen scattering.PACS number(s): 34.8G.Bm Various formalisms have been developed over the years
