Our work on analytically continued scattering theory based on the Schrodinger equation is reviewed. We give a brief description of how resonances, here defined as partial wave S-matrix poles, can be calculated as complex eigenvalues to the complex sc

In this paper we investigate the higher-order spectral properties of an electromagnetic (EM) transmission channel. We use higher-order moments ensemble averaging of received real underwater EM pulses for signal to noise enhancement and discuss approp

For pt.I see ibid., vol.20, p.1295 (1987). The exterior complex rotated continuum X alpha model described in an earlier paper is analysed and refined. In the present improved continuum electron exchange model the authors have the possibility of inclu

The exterior complex dilatated electron-atom scattering model of Krylstedt et al. is improved and further analysed. The authors propose the use of a so-called asymptotically completed form of local-density-based continuum exchange. This formulation i

An additive Mittag-Leffler type of partial-wave S-matrix expansion based on resonance poles, their corresponding residues plus a background integral is presented. A particular decomposition of this expression is studied in detail, and the authors emp

The authors propose the use of the complex coordinate method in conjunction with a local-density, X alpha static exchange plus polarisation model for the analysis of shape resonances in electron-atom scattering with possible extension to electron-mol

The dielectronic recombination cross sections associated with the 2s\ensuremath{\rightarrow}2p transition in Li-like carbon and oxygen ions in the presence of small electric fields have been calculated in the distorted-wave approximation. By convolut
