Specific distortion effects in the five-nucleon system

The effects of specific distortion in the channel spin (3/2) state of the d${+}^3$He system are considered by including in the resonating-group formulation inelastic channels involving deuteron pseudo-states. The result shows that, because of the high compressibility of the deuteron cluster, these effects are quite important in the l=0 configuration. With specific distortion taken into account, it is found that a satisfactory explanation of the experimental data on d${+}^3$He resonance state and scattering angular distributions can be achieved.
