| 英文摘要 | There are many rotating spheroids in the universe, and many astronomers and physicists have used theoretical methods to study the characteristics of stellar gravity since Newton's time. This paper derives the solutions of eight scattering states (phi((0)), chi((0)), phi((1)), chi((1)), phi((2)), chi((2)), phi((3)), and chi((3))) for the Dirac equation with positive-energy E = im, and establishes the relationship between the differential scattering cross section sigma(i)(p, theta, phi) and the stellar density mu. It is found that: (1) For the eight scattering states, their average scattering cross-sections (sigma(i)) over bar are proportional to mu(2), and depend on the star's radius, and the higher the stellar density mu, the greater the sensitivity of (sigma(i)) over bar to the change of mu; (2) For the four scattering states chi((i)), i = 0, 1, 2, 3, their average scattering amplitudes f (p, theta) and (sigma(i)) over bar (p, theta) depend on themass m of the particles; while for the other four scattering states phi((i)), i = 0, 1, 2, 3, then (f) over bar and (sigma) over bar are independent of m. This study links the gravitational characteristics of stars with the scattering cross section, creating a new method for studying the gravitational characteristics, which helps to reveal the mystery of the gravity of rotating ellipsoidal stars. |
