Description
Quantum systems with a strangeness degree of freedom are very important as
they provide an extra dimension, and hence a deeper insight into nuclear matter. Usually
phenomenological potentials obtained through meson exchange theories are used in investigating
these hypernuclear systems. In this paper potentials for lambda-nucleon interactions in the
spin singlet and spin triplet states, constructed through fixed-angular momentum inversion
based on Marchenko theory, are presented. Owing to experimental difficulties in obtaining a
sufficient number of lambda-nucleon scattering events, theoretical phase shifts are used as input
for the inversion. The constructed potential is energy-independent, making it more suitable for
quantum-mechanical few-body calculations.
