Abstract

Cross section and analyzing power Ay of $^2 {\rm H}(\vec p,p)pn$ reaction at $E_{\vec p} = 247\, {\rm MeV}$ were measured and large disagreements with 3N calculations were found especially at forward angles. Effects of 2π3NF are too small to explain the discrepancy. To microscopically investigate the discrepancy, a 2H(p, pp)n experiment is planned. [ABSTRACT FROM AUTHOR]

11. MEASUREMENT OF OFF-PLANE STAR ANOMALY IN pd BREAKUP AT Ed = 26 MeV.

Abstract

At Ed = 26 MeV, H(d,pp)n cross section was measured at 4 angle pairs corresponding to off-plane star and compared with recent pd calculations. A rotary foil target was developed for this experiment. The present data and previous data revealed dependence of the star anomaly on the star-inclination angle α. The angular dependence at Ep = 13 MeV differs much with that at 9.5 MeV.

12. MEASUREMENT OF OFF-PLANE STAR ANOMALY IN pd BREAKUP AT Ep = 9.5 MeV AND Ep = 13 MeV.

Abstract

We measured D(p, pp)n cross section at Ep = 9.5 MeV and 13 MeV at off-plane star configurations, including the space star where the star is perpendicular to the beam axis. The experimental results were compared with recent pd breakup calculations using screened Coulomb force, and disagreement was found to smoothly vary with an inclination angle of the off-plane star, α. Further systematic experiments are necessary to investigate the star anomaly. [ABSTRACT FROM AUTHOR]

Systematic measurement of D(p,pp)n cross section has been made at an incident energy of 13MeV around the space star configuration. In spite of the anomaly found in nd breakup cross section, no anomaly has been found in pd breakup. [ABSTRACT FROM AUTHOR]

EQUATIONS of state, NUCLEAR matter
Abstract

The equation of state(EOS) of nuclear matter is studied up to the three-hole-line level of approximation in the Behte-Brueckner-Goldstone expansion. The results indicate a good convergence of the theory. The fact that the resulting EOS does not reproduce the empirical saturation point suggests that the three-body forces are most likely the main term missing in the nuclear Hamiltonian.

Abstract

Precise measurements of the deuteron to proton polarization transfer coefficients for the d-p elastic scattering have been made at 135 MeV/u at RIKEN Accelerator Research Facility. The obtained results are compared with the Faddeev calculations based on modern nucleon-nucleon forces together with Tucson-Melbourne, Tucson-Melbourne' and Urbana-Argonne type of three nucleon forces.
