New method in elastic light scattering from Mie-particles

2007
Particles in the size range 200 < D < 2000 rim have enough information in their scattering function for a general interpretation procedure. The experimenter is faced with two basic problems. There is an essential loss of information caused by the cutoff, and the scattering theory of Mie has to be used for the description of the scattering process.

How French sheds new light on scalar particles

2017
Abstract This paper examines the behavior of the French scalar focus-sensitive particles même, quand même, ne serait-ce que, and seulement as compared to English even and only. I first show that French même displays a more restricted distribution than even; this behavior and that of its antonym quand même argue for the scope

New Physical Principle for Interference of Light and Material Particles

2017
Abstract To describe wave interference, a wave function with a direct physical meaning is used. On the contrary the distribution of material particles in an interference pattern is calculated with a probability wave function whose interpretation presents controversial features. Here, a general law is reported which provides a unified explanation of

A new solution of the light scattering problem for axisymmetric particles

Journal of Quantitative Spectroscopy and Radiative Transfer, 1999
Abstract A new approach to solve the problem of light scattering by particles with an axial symmetry is suggested. We divide the electromagnetic fields in two parts (an axisymmetric part having no dependence on the azimuthal angle and a non-axisymmetric part whose averaging over this angle gives zero) and consider the scattering problem separately ...

Light Scattering by Small Particles and Their Light Heating: New Aspects of the Old Problems

2014
A survey of recent results in light scattering by nanoparticles is presented. Special attention is paid to the case of particles from weakly dissipating materials, when the radiative damping prevails over the dissipative losses. It makes the scatter- ing process completely different from the Rayleigh one.

Astrophysical constraints on a new light axion and other weakly interacting particles

Physical Review D, 1982
Constraints on the light axion of Dine, Fischler, and Srednicki are critically reexamined and upper bounds on its mass are derived from stars at various stages of evolution. A conservative upper bound for the axion mass is about 1 eV, while a model-dependent argument gives a better upper bound of mass approx.0.07 eV.

New aspects on the tunneling of light interstitial particles in solids

Physica B: Condensed Matter, 1994
Abstract Recent experiments on the mobility of light interstitial particles (positive muons and muonium) in crystalline solids have revealed new aspects on the conditions for tunneling of these objects and the interplay with inelastic processes which leads to loss of coherence in the tunneling.
