The arrival of tunable dye lasers in the 1970s allowed a much greater level of control over populations of excited atoms.
22.
As these excited atoms decay to lower states, they will emit photons, which can then be detected and a spectrum can be determined.
23.
Excited atoms with very high values of the principal quantum number, represented by " n " in the Rydberg formula, are called Rydberg atoms.
24.
The device uses a high-energy laser to excite atoms, which then can be identified by the unique spectra of the light they give off.
25.
Without forming the excimers, the energy of the excited atoms would be rapidly lost by non-radiative collisional decay processes in the high pressure environment.
26.
The Auger effect is an electronic process at the heart of AES resulting from the inter-and intrastate transitions of electrons in an excited atom.
27.
In quantum optics, superradiance is a phenomenon that occurs when a group of N emitters, such as excited atoms, interact with a common light field.
28.
In this case, the relativistically moving excited atoms in the jets appear to vibrate more slowly and their radiation thus appears red-shifted ., p . 508.
29.
The effect is caused by a so-called Rydberg blockade, which, in the presence of one excited atom, prevents nearby atoms from being excited to the same degree.
30.
The ionization process involves an interaction between the analyte molecule ( S ) and electronically excited atoms or vibronically excited molecules ( metastable species M * ):
