Hyperspherical adiabatic potentials for 3-fermion threshold interactions

The interest in trapping of cold particles and other low-energy phenomena has stimulated research on threshold processes for three body systems. Such processes are efficiently modeled using the adiabatic hyperspherical representation. For threshold processes the behavior of the adiabatic curves at large hyperradius play a crucial role. These curves may be modeled using energy dependent zero range potentials. We employ such potentials for the case of three fermions where the two-body systems can be bound in p-wave bound states. Calculated adiabatic potential curves are presented.
