WebDec 18, 2013 · 4. Conclusions. Our model makes various simplifications, but describes the data for pp scattering well and for p ¯ p scattering quite well, over a wide range of energy. Our simplifications include: • making the three form factors F i (t) identical and of the simple form (1c);. making the trajectories α i (t) linear;. making the ρ and ω trajectories … WebThe elastic cross section is highly suppressed at these impact parameters because of the small phase space for thermal decay into a high energy two body state. For very large impact parameter the amplitude is dominated by eikonalized single graviton exchange. ... At intermediate impact parameters the scattering is more complicated, but since ...
WebThe scattering wave functions that are solutions of this equation must, from Eq. (2.4.12), match smoothly at large distances onto the asymptotic form ψasym(R,θ) = eikz +f(θ) eikR R. (3.1.6) We will thus find a scattering amplitude f(θ) and hence the differential cross section σ(θ) for elastic scattering from a spherical potential. WebApr 1, 2013 · The elastic scattering cross section of keV electrons over large angles (>90°) is discussed. A comparison is made of the Rutherford cross section, the cross section obtained in the first Born approximation and that obtained by a partial wave calculation. ...
