EFFECTS OF 3-BODY FORCES IN THE H-3 BOUND-STATE

Calculations of the H-3 bound state wave function obtained with the pa ir-correlated hyperspherical harmonic method are presented for a varie ty of three-body force models. In each calculation the strength of the three-body force is adjusted to reproduce the observed binding energy . Wave functions obtained with different three-body forces are compare d, and results are presented in graphical form for both coordinate and momentum space. For these binding-energy equivalent calculations, the S- and D-state components of the wave function are largely insensitiv e to the details of the three-body force. However, significant sensiti vity is observed for the very small P-state components.
