Precision Measurement of the n-3He Incoherent Scattering Length Using Neutron Interferometry [PDF]
, 2009 We report the first measurement of the low-energy neutron-$^3$He incoherent scattering length using neutron interferometry: $b_i' = (-2.512\pm 0.012{statistical}\pm0.014{systematic})$ fm. This is in good agreement with a recent calculation using the AV18+

Enhanced incoherent scatter plasma lines [PDF]
Annales Geophysicae, 1996 Abstract. Detailed model calculations of auroral secondary and photoelectron distributions for varying conditions have been used to calculate the theoretical enhancement of incoherent scatter plasma lines. These calculations are compared with EISCAT UHF radar measurements of enhanced plasma lines from both the E and F regions, and published EISCAT VHF ...

Hierarchical Deconvolution for Incoherent Scatter Radar Data [PDF]
Atmospheric Measurement Techniques, 2021 Abstract. We propose a novel method for deconvolving incoherent scatter radar data to recover accurate reconstructions of backscattered powers. The problem is modelled as a hierarchical noise-perturbed deconvolution problem, where the lower hierarchy consists of an adaptive length-scale function that allows for a non-stationary prior and as such ...

Neutron incoherent scattering from KDP [PDF]
Solid State Communications, 1968 Abstract The incoherent, inelastic neutron cross section is derived for KH 2 PO 4 , following the model discussed by Tokunaga and Matsubara. This expression should give the dominant contribution of the proton tunneling motion to the cross section. Matsubara has given the coherent cross section for KDP.

Diffraction of an electromagnetic wave on a countless number of scatterers
Вісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка, 2022 Topicality. The task of finding the radar cross-section (RCS) of complex objects is of great importance. Usually, when creating radar stations, RCS is measured on real targets.

Inelastic neutron scattering in random binary alloys : an augmented space approach
, 2004 Combining the augmented space representation for phonons with a generalized version of Yonezawa-Matsubara diagrammatic technique, we have set up a formalism to seperate the coherent and incoherent part of the total intensity of thermal neutron scattering

Effect of incoherent scattering on shot noise correlations in the quantum Hall regime
, 2000 We investigate the effect of incoherent scattering in a Hanbury Brown and Twiss situation with electrons in edge states of a three-terminal conductor submitted to a strong perpendicular magnetic field.

Emergence of entanglement from a noisy environment: The case of polaritons [PDF]
, 2009 We show theoretically that polariton pairs with a high degree of polarization entanglement can be produced through parametric scattering. We demonstrate that it can emerge in coincidence experiments, even at low excitation densities where the dynamics is
