Amplitude of Elastic Scattering for the Region of Large Impact Parameters

摘要

Bu ?al??mada, sa??lma genli?inin analitikli?inin ve uniterli?inin gereklili?i incelenmi?tir. Gaussiyen yar?-potential kullan?larak, sa??lma genli?i matrisi i?in bir denklem elde edilmi? ve tesir kesitleri i?in bir formül elde edilmi?tir. Tesir kesitin ba??ml?l??? ve ileri sa??lmadaki genli?in ger?el b?lümünün momentum üzerindeki sanal k?sm?na oran? tart???lm??t?r. Kü?ük a??larda tesir kesiti i?in dik Gaussiyen zirveyi üstel (Orear) rejim takip eder. Teorik yakla??mdan elde edilen sonu?lar deneysel veriler ile kar??la?t?r?lm??t?r . The work is dedicated to consequences of analyticity and unitarity of the scattering amplitude. Using the Gaussian quasipotential an equation for the scattering amplitude matrix is obtained and formula is derived for the cross sections. The dependence of the cross section and ratio of the real part of the amplitude in the forward scattering to its imaginary part of on the momentum are discussed. The steep Gaussian peak for cross section at small angles is followed by the exponential (Orear) regime. Results from theoretical approach are compared with experimental data.
