The Atomic Hydrogen Maser [PDF]
IRE Transactions on Instrumentation, 1961 The atomic hydrogen maser is described. In this device hydrogen atoms in the upper hyperfine state are focused onto the entrance aperture of a Teflon coated quartz bulb in which the atoms are stored for about a second. This bulb is surrounded by a cylindrical radiofrequency cavity; When the cavity is tuned to the hyperfine frequency of atomic hydrogen,

Lithuanian Mathematical Journal, 2007 We represent the deterministic substitute of the Schrodinger equation for a hydrogen atom in precise accordance with the Bohm-de Broglie interpretation of quantum mechanics. To construct a mathematical model, the Weierstrass theorem and limit cycles are used. This method can be applied to many-electron atoms.

, 2010 Based on the discussions in Chap. 4 we will now apply the quantum mechanical treatment to the simplest atom, the H atom, which consists of one proton and one electron moving in the spherical symmetric Coulomb potential of the proton. These one-electron systems, such as the hydrogen atom and the ions He+, Li++, Be+++, etc., are the only real systems for

, 2014 In elementary quantum mechanics there are two important models that are exactly solvable, which means that the solution of the eigenvalue problem (from now on short for eigenvalue—eigenfunction problem) can be found in closed form.

We have here a two-body problem, of an electron of charge -e and mass m, and a proton of charge +e and mass M. By using CM and relative coordinates and working in the CM frame, we can reduce the problem to the dynamics of a single particle whose mass µ = mM /(m + M) is the reduced mass and whose coordinate r is the relative coordinate of the two ...

Hydrogen, the simplest of all the elements, has been investigated most extensively both experimentally and theoretically. The knowledge obtained from this study has acted as a guide to the study of more complex elements. In this chapter we limit our considerations to hydrogen; in the next two chapters we discuss more complicated elements.

The explanation of spectroscopic data was one of the first great victories of quantum theory. In modern science and technology, the mastery of atomic physics is responsible for decisive progress ranging from laser technology to the exploration of the cosmos.

The hydrogen atom in the hydrogen molecule
International Journal of Quantum Chemistry, 2009Accurate two-electron wavefunctions which are localized in the sense that they are least distorted from a product of hydrogen atom wave functions, have been calculated for the X, 1∑+ and the b3∑+ states of H2 at nuclear separations of 1.0 to 4.0 bohrs. The calculations were done in the full configuration interaction approximation.

Reactions of Hydrogen Atom with Hydrogen Peroxide
The Journal of Physical Chemistry A, 2007Rate coefficients are calculated using canonical variational transition state theory with multidimensional tunneling (CVT/SCT) for the reactions H + H2O2 --> H2O + OH (1a) and H + H2O2 --> HO2 + H2 (1b). Reaction barrier heights are determined using two theoretical approaches: (i) comparison of parametrized rate coefficient calculations employing CVT ...
