Classical Mechanics of Collinear Positron-Hydrogen Scattering
Min-Ho Lee, Chang Woo Byun, Jin-Sung Moon +2
We study the classical dynamics of the collinear positron-hydrogen scattering system below the three-body breakup threshold. Observing the chaotic behavior of scattering time signa…
Evidence of triple collision dynamics in partial photo-ionisation cross sections of helium
Gregor Tanner, Nark Nyul Choi, Min-Ho Lee +2
Experimental results on partial photo-ionisation cross sections of helium are analysed in the light of recent advances in the semiclassical theory of two-electron atoms. Byun et al…
Scaling laws for the photo-ionisation cross section of two-electron atoms
Chang Woo Byun, Nark Nyul Choi, Min-Ho Lee +1
The cross sections for single-electron photo-ionisation in two-electron atoms show fluctuations which decrease in amplitude when approaching the double-ionisation threshold. Based…
The classical dynamics of two-electron atoms near the triple collision
Min-Ho Lee, Gregor Tanner, Nark Nyul Choi
The classical dynamics of two electrons in the Coulomb potential of an attractive nucleus is chaotic in large parts of the high-dimensional phase space. Quantum spectra of two-elec…
Classical dynamics near the triple collision in a three-body Coulomb problem
Nark Nyul Choi, Min-Ho Lee, Gregor Tanner
We investigate the classical motion of three charged particles with both attractive and repulsive interaction.The triple collision is a main source of chaos in such three body Coul…
Infinite Order Discrete Variable Representation for Quantum Scattering
Nark Nyul Choi, Min-Ho Lee, Sung Ho Suck Salk
A new approach to multi-dimensional quantum scattering by the infinite order discrete variable representation is presented. Determining the expansion coefficients of the wave funct…
