and a further multiplication by ħω gives the radiation energy in this segment of the spectrum: (63.5)dEω=Vℏπ2c3 ω3dωeℏω/T−1. This formula for the spectral energy distribution of black-body radiation is called Planck's formula.† In terms of the wavelength λ = 2π...
However, many shape factors have been tabulated in books which simplify the analyses significantly. There are relations between shape factors which are useful for constructing complex shape factors from an assembly of more simple shape factors. Considerable time could be spent in this discussion; ...
The effect of radiation-reaction force on the dynamics of a charged particle in an intense focused light wave is investigated using the physically appealing Hartemann-Luhmann equation of motion. It is found that, irrespective of the choice of initial con
The electron's stability (the vanishing of total T μv , v ) is du to surface tension κ of the membrane, but the model is as simple as the point particle, with two parameters κ and e ; the surface tension parameter κ can be expressed in terms of the mass m . 展开 ...
We have examined an action term with wrong signs for both the kinetic and mass terms for the scalar field and have found solutions for both the scale factor of the universe and the Brans-Dicke scalar field which vary exponentially in time.Arik, Metin; Erkmen, Tunc...
InterSpec is a native or web application to assist in analyzing spectral nuclear radiation data, using a peak-based methodology. Common uses include identifying nuclides present, determining source activity, shielding amounts, source age, or other nuclear reactions present. InterSpec also provides a nu...
This method is based on the substitution of a matrix product for the radiative terms in the rate equation and the introduction of a symmetrical matrix, related in a simple way to the matrix representation of the radiation transfer probability space. Also, a vector proportional to the vector ...
The Wolf–Rayet (WR) binary system WR140 is a close (0.9–16.7 mas; ref. 1) binary star consisting of an O5 primary and WC7 companion2 and is known as the archetype of episodic dust-producing WRs. Dust in WR binaries is known to form in a confined str
