What is Atomic Number & Mass Number - The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. Visit BYJU'S to learn more about atomic numbers.
This communication is concerned with atomic emission of the 589.0/589.6 nm sodium doublet, in a N2/H2 diffusion flame on the sheathing gas box of a carbon filament atom reservoir. The sample is directly atomised by the carbon filament thechnique1.doi:10.1080/00387017308064981...

Here again there is a number of available tools developed to successfully deal with the difficult mathematical issues related to the space unbound nature of the continuum states involved. In both branches, the solutions of the hydrogenic atom played and still plays a fundamental role. Indeed, many...
Fluorescence detection was used to record the trapped atom number and the desorption rate. We observed a steep wavelength dependence of the desorption process above 2.6eV photon energy, a result significant for estimations of sodium vapor density in the lunar atmosphere. Our data fit well to a ...
