无质量标量波在Garfinkle Horowitz Strominger dilaton 黑洞背景时空中的散射

摘要：本文对Garfinkle-Horowitz-Strominger dilaton 黑洞背景时空中无质量标量波的Klein-Gordon方程分离变量，分别得到角向方程与径向方程.其中角向方程的'解是球谐函数.采用近似方法得到了径向方程的解.并利用分波法求出了微分散射截面.

Scattering of massless scalar wave in Garfinkle Horowitz Strominger dilaton black hole spacetime

Abstract: In this paper ,we separate the variables of the Klein-Gordon equation in Garfinkle Horowitz Strominger dilaton black hole spacetime. Angular equation and radial wave equation are obtained.The solution of angular equation is spherical harmonic function .We solve the radial equation by approximation method and find the differential cross section by partial wave expansion.

Keyword: scalar wave black hole partial wave expansion differential cross section
