Bremsstrahlung 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 کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولBremsstrahlung corrections to the decay b → sγ
We calculate the O(αs) gluon Bremsstrahlung corrections to the inclusive decay b → sγ, involving the full operator basis Ô1 – Ô8. Confirming and extending earlier calculations of Ali and Greub, we give formulas for the total decay width as well as the perturbative photon spectrum, regarding the former as a necessary part of the forthcoming complete NLO analysis. We explore in detail the renorma...
متن کاملInner bremsstrahlung accompanying β decay of 86Rb
Inner bremsstrahlung accompanying the first-forbidden beta decay of 86Rb was measured using the magnetic deflection technique with a 4.5 x 5.1 cm2 NaI(T1) crystal in the energy range 200-1660 keV. The raw spectrum was unfolded using the step-by-step process of Starfelt and Liden and compared with KUB, LF and FM theories. The measured spectrum is found to show fairly good agreement with LF theor...
