Description of two-electron atoms with correct cusp conditions

Autor: Kruppa, A. T., Kovács, J., Hornyak, I.

New sets of functions with arbitrary large finite cardinality are constructed for two-electron atoms. Functions from these sets exactly satisfy the Kato's cusp conditions. The new functions are special linear combinations of Hylleraas- and/or Kinoshi

Cross section measurement of the astrophysically important 17O(p,gamma)18F reaction in a wide energy range

Autor: Gyürky, Gy., Ornelas, A., Fülöp, Zs., Halász, Z., Kiss, G. G., Szücs, T., Huszánk, R., Hornyák, I., Rajta, I., Vajda, I.

Publikováno v: Phys. Rev. C 95, 035805 (2017)

The 17O(p,g)18F reaction plays an important role in hydrogen burning processes in different stages of stellar evolution. The rate of this reaction must therefore be known with high accuracy in order to provide the necessary input for astrophysical mo

Coulomb-distorted plane wave: partial wave expansion and asymptotic forms

Autor: Hornyak, I., Kruppa, A. T.

Publikováno v: J. Math. Phys. 54, 053502 (2013)

Partial wave expansion of the Coulomb-distorted plane wave is determined and studied. Dominant and sub-dominant asymptotic expansion terms are given and leading order three-dimensional asymptotic form is derived. The generalized hypergeometric functi

Two-body Coulomb scattering and complex scaling

Autor: Hornyak, I., Kruppa, A. T.

The two-body Coulomb scattering problem is solved using the standard complex scaling method. The explicit enforcement of the scattering boundary condition is avoided. Splitting of the scattering wave function based on the Coulomb modified plane wave
