Question. The ionization energy of the electron in the hydrogen atom in its ground state is 13.6 eV. The atoms are excited to higher energy levels to emit radiations of 6 wavelengths. Maximum wavelength of emitted radiation corresponds to the transition betweenC a) n = 3 to n = 1 states...
The calculations are carried for fixed scattering angles and ejected electron energies at the impact energies 75, 200, and 500keV. The influence of each of the incidence energy and the atomic number of the target atom on the TDCSs is studied. The contribution of the second-Born term to the...
For a hydrogen atom, posed of an orbiting electron bound to a nucleus of one proton, an ionization energy of 2.18 × 10−18joule (13.6 electron volts) is required to force the electron from its lowest energy level entirely out of the atom. The magnitude of the ionization energy of an ...

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:
A theoretical study of the ionization of hydrogen atoms by short external half-cycle pulses (HCPs) as a function of the pulse duration, using different quantum and classical approaches, ispresented. Total ionization probability and energy distributions of ejected electrons are calculated in the ...
Cross sections for charge transfer and ionization of atomic hydrogen by highly charged ions A(q+) (q = 6-9) are evaluated using a simple and classical method based on the previous works by Bohr and Lindhard [K. Dan. Vidensk. Selsk. Mat. Fys. Medd 28 (1954) No 7], Brandt [Nucl....
Role of projectile continuum states in the ionization of atomic hydrogen by high-energy ion impact Ionization of atomic hydrogen in collisions with H+ and He2+ ions is studied by a large-scale coupled-channel calculation. It is demonstrated that high-lyi... N Toshima - 《Journal of Physics ...
As the scaled energy is close to the saddle point energy, the ionization process of the hydrogen atom is nearly the same as the case of hydrogen atom in an electric field. There is only a single pulse of electrons, with an exponentially decaying tail. With the increase of the scaled ...
