In this paper, the spectral properties of ʟ such as the spectrum, the eigenvalues, the scattering function and their properties are investigated. Moreover, an example about the scattering function and the existence of eigenvalues is given in the special cases, if (Formula Presented).trueHyperbolic parameter | Impulsive condition | Klein-Gordon equations | Scattering function | Spectral analysisArticle10.35378/gujs.88145910.35378/gujs.8814592-s2.0-85140066121WOS:0009048703000261614162235
