- Abstract
In this paper we analyze the Schr $$\ddot{o}$$ dinger-type scalar wave equation from JNW naked singularity spacetime and numerically investigate its absorption and scattering cross section. We find that total absorption cross section curve becomes lower as the coupling parameter $$\nu $$ becomes bigger, the width of the main scattering angle becomes narrower and the peak of differential scattering cross section becomes higher as the angular momentum $$l$$ increases. With fixed frequency $$\omega $$ of scalar wave, the glory peak becomes lower and the glory width becomes narrower while increasing the coupling parameter $$\nu $$ .
