New parameterization of the trinucleon wavefunction and its application to the $π^3$He scattering length

Authors

Description

We present a new parameterization of the trinucleon wavefunction. As a novel feature a separable parameterization for the complete wavefunction is given. In this way any calculation that considers two body forces only is largely simplified. To demonstrate this we calculate the $π^3$He scattering length.
