  • 本文将Schwarzschild度规中的二分量Dirac方程(Brill-Wheeler方程)化为一个单分量的二阶方程,考查了方程的有效势,找出了自旋轨道耦合项。视界附近是一个势垒,当K2>3η2,势垒外侧出现势阱。Dirac粒子将在势阱中某些能级上共振,并穿越势垒被视界吸收。借WKB方法求得准束缚态的能谱,并计算了大|K|情形下的寿命。同样的处理方法还推广至Reissner-Nordstrom度规。
    In this paper, the two-component Dirac equation in Schwarzschild background space time is reduced to a one component second order equation. The effective potential and the L-S coupling term are given. Near the horizon, there is a potential wall. When K2>3η2, there is another potential well by the wall. So the particle resonating in the well will be absorbed by the horizon after penetrating through the wall. With WKB approximation, the resonance spectrum and its width are obtained. For the case of Re-issner-Nordstrom background space time, the same procedure is also carried out, and the results are discussed briefly.
