Abstract

We investigate the multipole polarizabilities of negatively charged helium-like ions interacting with exponential-cosine-screened Coulomb potentials using correlated exponential wave functions. The dynamic dipole and quadrupole polarizabilities of negatively charged helium-like ions \(^{\mathrm {\infty }}\)H\(^{\mathrm {-}}\), \(^{\textrm{1}}\)H\(^{\mathrm {-}}\), D\(^{\mathrm {-}}\), T\(^{\mathrm {-}}\), Mu\(^{\mathrm {-}}\), Pi\(^{\mathrm {- }}\)are presented as functions of screening parameter. The static dipole and quadrupole polarizabilities, and the ground state energies are presented in terms of nuclear mass and screening parameter.

期刊介绍： The journal Few-Body Systems presents original research work – experimental, theoretical and computational – investigating the behavior of any classical or quantum system consisting of a small number of well-defined constituent structures. The focus is on the research methods, properties, and results characteristic of few-body systems. Examples of few-body systems range from few-quark states, light nuclear and hadronic systems; few-electron atomic systems and small molecules; and specific systems in condensed matter and surface physics (such as quantum dots and highly correlated trapped systems), up to and including large-scale celestial structures. Systems for which an equivalent one-body description is available or can be designed, and large systems for which specific many-body methods are needed are outside the scope of the journal. The journal is devoted to the publication of all aspects of few-body systems research and applications. While concentrating on few-body systems well-suited to rigorous solutions, the journal also encourages interdisciplinary contributions that foster common approaches and insights, introduce and benchmark the use of novel tools (e.g. machine learning) and develop relevant applications (e.g. few-body aspects in quantum technologies).
