The ground-state energy of the helium atom in a plasma is calculated by the variational method with the static screened Coulomb potential as the interparticle potential. This is used to calculate the ionization energy of the helium atom as a function of the screening parameter. The critical value...
As a test case, the method is applied to calculate triple differential cross sections for electron impact ionization of H atom at an excess energy of 4 eV for the coplanar th12 = p geometry. The results are obtained for both equal and unequal energies of the two outgoing electrons in the...
Experiments were carried out at the LCLS, a national user facility operated by Stanford University on behalf of the US Department of Energy (DOE), Office of Basic Energy Sciences. The authors acknowledge support from the Max Planck Society for funding the development and operation of the CAMP in...
Ionization of atomic hydrogen by antiproton impact:A direct solution of the time-dependent Schrdinger equation We present a theoretical study on the ionization of a H atom by antiproton impact in a wide energy range (from 0.1 to 1000 keV). Taking a semiclassical approximation, in which the ...
The ionization potential of hydrogen atom is 13.6 eV. The energy required to remove an electron from the n = 2 state of the hydrogen atom is:
Our primary focus in this work has been upon the relationship between atomic polarizability and volume, although we also looked at the role of ionization energy. For approximating volumes in this context, we tried ten different measures of atomic radii, based upon both empirical and theoretical cri...
The ionization energy is the energy required to completely remove a valence electron from a gaseous atom or ion. What is meant by a gaseous ion? Logged Borek Mr. pH Administrator Deity Member Posts: 27904 Mole Snacks: +1817/-412 Gender: ...
Comparing the estimated initial kinetic energy of the atoms (B1.6 MHz) with the depth of the trapping potentials (1.1 and 3.1 MHz for F and G, respectively), we expect atoms in level G to be trapped at locations where the intensity at the atomic nucleus is high; this is illustrated in...
Capture, excitation and ionization cross sections have been calculated for the H+He(1s) reaction up to v=3 a.u. in a sole theoretical formalism. An extension to the intermediate energy range of the molecular method including distorded molecular orbitals to discretize the continuum is used. Our...
