Excited hydrogen atoms

C07-0126. The series of emission lines that results from excited hydrogen atoms undergoing transitions to the n — 3 level Is called the Paschen series. Calculate the energies of the first five lines In this series of transitions, and draw an energy level diagram that shows them to scale. 

FIGURE 5.6 (a) The visible line spectrum of energetically excited sodium atoms consists of a closely spaced pair of yellow lines, (b) The visible line spectrum of excited hydrogen atoms consists of four lines, from indigo at 410 nm to red at 656 nm. 

Excited hydrogen atoms give off a bluish light excited neon atoms emit orange light. 

This effect has been thoroughly investigated in numerous experiments that result in the following conclusion the interaction of the excited hydrogen atom with a metal surface has a specific nature and only phenomenologically can be... 

As shown in Fig. 5.1, since excited hydrogen atoms can be produced by dissociation of hydrogen molecules and molecular ions, the hydrogen molecules can affect emission from the hydrogen atoms. Therefore, by investigating emission from the hydrogen atoms, we can study hydrogen molecule behav-... 

We perform numerical modeling of atomic processes in various real plasmas including LHD fuel-pellet ablation and short-pulse laser interaction plasmas [21], We are developing a mixed quantum-classical code to study excited hydrogen atom formation in neutrals of back scattered protons at wall surfaces.

An excited hydrogen atom emits light with a wavelength of 397.2 nm to reach the energy level for which n = 2. In which principal quantum level did the electron begin ... 

The second class of atomic systems studied in the search for manifestations of chaos consists of time-dependent Hamiltonian systems such as one-electron atoms in an oscillating field. The hydrogen atom in a microwave or laser field is the standard physical example and has been a focus of attention since the ionization of highly excited hydrogen atoms by intense microwave fields was first observed by Bayfield and Koch in 1974 [10]. 

When hydrogen gas was introduced into argon plasma jet, all the argon emissions were strongly quenched and a very short and brilliant flame with a light blue color was formed. The emissions from excited hydrogen atoms (E 12 eV) and molecules (E 11.8eV) were...
