The objective of the paper is openly to invite all physicists, mathematicians and engineers in the world to re-examine and to confirm the ultimate truth and the worldwide impacts of two U.S. Basic Patents No.5,084,232 and No. 5,848,377 which can be obtained from: http://164.195.100.11/netahtml/srchnum.htm The application of Trajectory Solid Angle (TSA) to obtain the correct collision cross-sections in Nuclear Physics and in Astronomy by the example of obtaining the correct scattering cross-section of the well- known Alpha Scattering was shown in a paper IAF-00-J.1.10. entitled " Applications of Trajectory Solid Angle (TSA) and Wong's Angles (WA) Solving Fundamental Problems in Physics and Astronomy " presented and published at the 51st. International Astronautical Congress, 2-6 Oct 2000/Rio de Janeiro, Brazil. The Alpha Scattering was done in theory and in experiment by Sir Rutherford. The differential scattering cross section derived from using the geometric solid angle can be seen from all the text books of physics in the world. However, the differential scattering cross section derived from using the TSA has not been known by most of our colleagues in the world and it is different from the previous results. The present and the previous theoretical results converge to be the same only when the Alpha particle is far away from the stationary heavy nucleus. That was where Sir Rutherford made his measurement and therefore the old theory and the experiment were confirmed. The Alpha Scattering is really similar to the scattering of the Comet Halley by our solar system even though they are under the actions of different force fields. In 1976-79, the senior author of this paper communicated with JPL of NASA and urged JPL to conduct an experiment to confirm the curvature effects of the trajectory of the Comet Halley coming closer to our solar system in those years. It is unfortunate that the communications have never been answered even up to now. Without repeating the analysis, the trajectory equation can be expressed by means of the spherical coordinate system that was shown in the paper IAF-00-J.1.10 Ref. 2 Figure No.1 and in Ref.3 Figure No. 1 for axially symmetric motion. The scattered particle is restricted in a plane surface which is perpendicular to the XOY plane; the particle is coming from the negative Z axis going upward as the altitude angle @ that is measured from the XOY plane as zero degree. After going through all the process as indicated in the above example A. of the paper IAF-00-J.1.10, the differential trajectory solid angle can be obtained as (2 pi (e)(Sin @)^2 d @)/((1+eCos @)^2 + (e Sin @)^2) ^(1/2) that is obviously different from the usual differential geometric solid angle obtained as 2pi Sin @ d@ where e is the eccentricity of the orbit and pi = 3.14159....... This paper will be concentrated in the presentation and publication of the graphical results of numerical data obtained from the above two differential scattering cross-sections in greater detail in order to distinguish the differences by Comparison of the Trajectory Solid Angle (TSA) with the Geometric Solid Angle (GSA) in Scattering Theory for the Central Force Fields.
