The ionisation probability presents different sharply peaked, non-symmetric local maxima as a function of the confinement size. This behaviour is related to the energy of the initial confined state that presents several maxima and minima in a kink-like structure as a function of the confinement ...
where [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.] the dimensionless parameters [[theta].sub.s] and [[eta].sub.s] represent the reduced binding energy of the electron and the reduced proton energy; a0 is the radius of the first Bohr orbit of the hydrogen atom; [Z.sub.S] = Z-...

Absolute triple differential cross sections (TDCS) of the electron impact ionisation of helium and relative measurements on atomic hydrogen will be presented at an impact energy of 2 eV above the ionisation threshold with the outgoing electrons sharing the excess energy to E 1 = E 2 = 1eV. ...
The triple differential cross section for ionisation of hydrogen atoms in the metastable 2s-state by electrons of 250 eV incidence energy has been calculated following the multiple scattering theory of Das and Seal (1993). The results ar... S Dhar - 《Australian Journal of Physics》 被引量: ...
Another piece of fluorite which did not transmit the ionising light was transparent to about ;\1350. Prof. Lyman's researches show that the hydrogen discharge emits very intense ultra-violet light distributed over a large number of wave-lengths between ;\1200 and }..1600. Hence, with thin ...
The ionisation enthalpy of hydrogen atom is 1.312×106 J mol−1. The energy required to excite the electron in the atom from n = 1 to n = 2 is A8.51×105J mol−1 B6.56×105J mol−1 C7.56×105J mol−1 D9.84×105J mol−1Submit ...
The absolute coplanar asymmetric triple differential cross section data of Schlemmer et al. (1985) for the ionisation of atomic hydrogen at an incident electron energy of 150 eV and scattering angle of 16 degrees are employed to demonstrate that higher-order (n>2) terms of the scattering amplitu...
