Electron polarimetry with bremsstrahlung
Due to the spin-orbit interaction, the electron scattering from the nucleus is sensitive to the spin orientation of that electron. This is used for polarimetry of electron beams in the Mott method. The spin-orbit interaction was also observed in bremsstrahlung. In this article we analyze its potential for polarimetry as an alternative to the Mott method. It can simultaneously measure all three ...
متن کاملRelativistic effects in polarizational bremsstrahlung
We review the achievements of the theory of polarization bremsstrahlung of relativistic particles, including the case when both colliders have internal structure. The main features which the relativistic effects bring into the problem are discussed and illustrated by the results of numerical calculations.
متن کاملBremsstrahlung Spectrum in α Decay
Using our previous approach to electromagnetic emission during tunneling, an explicit , essentially classical, formula describing the bremsstrahlung spectrum in α decay is derived. The role of tunneling motion in photon emission is discussed. The shape of the spectrum is a universal function of the ratio E γ /E 0 , where E γ is the photon energy and E 0 is a characteristic energy depending only...
متن کاملAnalytic Solution of Bremsstrahlung TBA
We consider the quark–anti-quark potential on the three sphere or the generalized cusp anomalous dimension in planar N = 4 SYM. We concentrate on the vacuum potential in the near BPS limit with L units of R-charge. Equivalently, we study the anomalous dimension of a super-Wilson loop with L local fields inserted at a cusp. The system is described by a recently proposed infinite set of non-linea...
متن کاملBeam-size Effect in Bremsstrahlung *
The smallness of the transverse dimensions of the colliding beams leads to suppression of bremsstrahlung cross section. This beam-size effect was discovered and investigated at INP, Novosibirsk. Different mechanisms of radiation are discussed. Separation of coherent and incoherent radiation is analyzed in detail. For linear collider this suppression affects the whole spectrum. It is shown that ...
