無質(zhì)量標(biāo)量波在Garfinkle Horowitz Strominger dilaton
無質(zhì)量標(biāo)量波在Garfinkle Horowitz Strominger dilaton 黑洞背景時(shí)空中的散射
摘要：本文對(duì)Garfinkle-Horowitz-Strominger dilaton 黑洞背景時(shí)空中無質(zhì)量標(biāo)量波的Klein-Gordon方程分離變量，分別得到角向方程與徑向方程.其中角向方程的解是球諧函數(shù).采用近似方法得到了徑向方程的解.并利用分波法求出了微分散射截面.
關(guān)鍵詞：標(biāo)量波; 黑洞; 分波法; 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
