Abstract
Modifications needed in order that low energy singlet scattering be described when a repulsive core is introduced in a phenomenological nucleon-nucleon interaction are investigated. It is found that if a square well is used to represent the attractive part of the interaction, a range of potential parameters allows a description of the data and also satisfies the charge independence hypothesis. When the Yukawa potential is investigated, the assumption of charge independence is more restrictive, and a single set of parameters is found.
