It is shown that a formula for the intensity of optical emission lines is in very good agreement with experimental results reported in standard tables of spectral data. It is emphasized that the formula is consistent with main features of the spectrum of the Sun. The formula is: I(h nu) ...
An empirical formula for the wave numbers of various lines of certain spectral series such as neutral hydrogen and alkali metals; it states that the wave number of thenth member of the series is λ∞-R/(n+a)2, where λ∞is the series limit,Ris the Rydberg constant of the atom, andais...
Experimental correction of the formula for linear dispersive power and its use in automatically seeking positions of spectral lines by computer The corrected formula can directly be used to work out a computer program for automatically seeking places for spectra. It makes the program simple, its .....
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.The Rydberg formula is used in atomic physics to describe the wavelengths of spectral lines of many chemical elements. The formula was invented by the Swedish physicist Joha...
It is shown, for the first time to our knowledge, that the standard Lamb shift formula for non-S-states of hydrogenic atoms can be derived by applying the methods of nonrelativistic quantum electrodynamics and without using the Dirac equation and the second quantization for the electron.关键词:...
Polarisation of Spectral Lines Polarisation effects can be associated with the lines related to Zeeman splitting. Polarisation in this context refers to the direction of the vibration of electromagnetic field lines. For example, polarising sunglasses usually suppress ambient glare because light reflected fr...

Our result for the line intensity is in agreement with the high-resolution transmission molecular absorption database value but 1.4% smaller. It was applied to partial pressure measurements of <formula formulatype="inline"><tex>$hbox{CO}_{2}$</tex></formula> in <formula formulatype="inline"...
The lower limit on the mass of the compact object is higher than the maximum mass of a rotating neutron star based upon equations of state for nuclear material. Subtraction of the correctly broadened template star removes all lines other than a line at 6708 Å which we identify as Li i ...
