Abstract
A shape resonance in lying above the n=2 Ps threshold is calculated using the method of complex-coordinate rotation with Hylleraas-type wave functions. Comparison is made with a calculation using adiabatic potential curves. We also report new results for shape resonances lying above the n=3 and 7 thresholds.
