Hyperpolarizability of the hydrogen atom

Physical Review A, 1987
The frequency dependence of the hyperpolarizability (\ensuremath{\gamma}) of the nonrelativistic hydrogen atom is calculated for a range of third-order nonlinear optical processes using an expansion in Sturmian functions. It is shown that the quantitative relations between the various nonlinear optical processes are made much clearer when \ensuremath ...

The Hydrogen Atom

2012
Some of the problems that were the center of discussions during the long genesis of the quantum theory were the atomic structure and the radiated spectral lines, in particular the emission lines of Hydrogen. A convincing explanation of this problem had to wait to the advent of the quantum theory.

The Hydrogen Atom

1973
In non-relativistic theory the hydrogen atom is one of the few cases for which the Schrodinger equation may be solved exactly. For this to be possible the proton and electron are assumed to be spinless, and the only role that the proton plays is to provide an attractive Coulombic potential; the finite mass of the proton may, of course, be taken into ...

Atomic hydrogen stabilized

Nature, 1980
Silvera and Walraven's report (Phys. Rev. Left. 44, 164; 1980), that they have succeeded in stabilizing bulk atomic hydrogen, suggests that the preparation of superfluid hydrogen may become a practical proposition in the not too distant future.

Atomic hydrogen in the

The 13th international winterschool on electronic properties of novel materials- science and technology of molecular nanostructures, 1999
Contrary to nitrogen and phosphorous, atomic hydrogen is not stable in C60 at room temperature. However, recently it was reported that hydrogen can be stabilized the a cube-like cage of Si8O12. In the present experiment the endohedral system H@Si8O12Et8 (Et=ethyl) was produced by ion implantation using ion implantation on a growing Si8O12-film.

Quantum Mechanics of the Hydrogen Atom

1983
In this chapter, we shall solve the Schrodinger equation of the hydrogen atom. For our calculations, we will not initially restrict ourselves to the Coulomb potential of the electron in the field of the nucleus of charge Z, V(r) = − Ze 2/(4πe0 r), but rather will use a general potential V(r), which is symmetric with respect to a centre.

Bohr’s Model of the Hydrogen Atom

1983
In the following chapters we shall take up the detailed analysis of the spectra of atoms in every wavelength region. The most important sources of information about the electronic structure and composition of atoms are spectra in the visible, infrared, ultraviolet, x-ray, microwave and radio frequency ranges.

Hydrogen Atom

2010
Publisher Summary The hydrogen atom has only one electron. The wave function ψ(r) of the electron in the hydrogen atom satisfies the Schrodinger equation. The hydrogen atom consists of a proton and an electron, and has a spherical symmetry that can most easily be studied using a spherical polar coordinate frame. Although the energy of an electron in a
