We study the effect of s-wave cross-sections in 4He+n and 9Li+n elastic scattering reactions by using the Jost function method (JFM). In 5He (4He+n), the s-wave pole of the S-matrix does not contribute so much to the total cross-section. On the other hand, in 10Li (9Li+n), the s-wave component can not be neglected due to a relatively strong attraction for the s-waves of the core+n potential. It...

The Evans function is a Wronskian type determinant used to detect point spectrum of differential operators obtained by linearizing PDEs about special solutions such as traveling waves, etc. This work is a sequel to the paper “Derivatives of (modified) Fredholm determinants and stability of standing and traveling waves”, published by F. Gesztesy, K. Zumbrun and the second author in J. Math. Pure...

Although it is tempting to think that one’s political convictions reflect independent and unbiased thinking, research increasingly suggests that ideologies reflect motivational processes. The present paper integrates system justification and shared reality theories to propose that ideologies may function as prepackaged units of interpretation that spread because of basic human motives to unders...

In this paper, an approach to solving direct and inverse scattering problems on the half-line for a one-dimensional Schrödinger equation with complex-valued potential that is exponentially decreasing at infinity developed. It based power series representation of Jost solution in unit disk complex variable related spectral parameter by Möbius transformation. This leads efficient method correspon...
