Natural Parity

Inelastically scattered IX-particles from the reaction 32S(IX, 1X')32S have been studied with solid state counters at extreme backward angles in order to determine spin-parity combinations for levels in 32S at excitation energies Ex up to 7 �15 MeV. The results confirm the well-established spin and parity values, show that the 5� 798 MeV spin 1 state has negative parity, and provide narrow limits for the possible spin and parity values of the 6'410,6' 666,6' 762, and 6� 854 MeV levels. A previously unreported natural parity level was found at Ex = 6�58 MeV. Magnetic analysis of the reaction 32S(p, p')32S confirmed the existence of this level and established its excitation energy as 6�581�0�003 MeV. Particle-y-ray coincidence studies showed that this level decays predominantly by y-ray transitions to the 2�23 MeV 2 + state.

Natural Parity

The theoretical studies of (K−, π−) and (π+, K+) reactions on p-shell targets are presented in the DWIA framework with use of the elementary spin-nonflip and spin-flip amplitudes. Calculations can explain the available experimental data of excitation functions and angular distributions of the (K−, π−) reactions at pK−=800 MeV/c and the (π+, K+) reactions at pπ+ = 1.04 GeV/c. Characteristic and distinguished features of the excitation functions and cross sections are exhibited. Especially it is demonstrated that the (K−, π−) reactions at pK−=1.1 GeV/c and 1.5 GeV/c can excite the unnatural parity states with comparable strength to the natural parity ones. Further interesting is that the (π+, K+) and (K−, π−) reactions with ∼1 GeV/c incident beams can be shown to produce very large polarizations of the produced hypernuclear states. Taking the subsequent deexcitation processes of the excited states into account, we have evaluated the hypernuclear polarization and Λ-spin polarization of the ground state and/or the ground-doublet states at the hypernuclear weak-decay stage, which would play a role in the hypernuclear coincidence experiment.

Good Agreement

The absence of exotics and the natural parity exchange dominance in the t-channel, in high energy meson photoproduction of nucleons impose, via duality, restrictions on the baryonic resonance photocouplings. In a broken SU(6)w parametrization these constraints allow different couplings for the [Formula: see text] and [Formula: see text] baryonic resonances and impose relations between the transitions to the 70 and 56SU(6)W representations. It is shown that the low energy baryonic resonance photocouplings are in good agreement with these high energy constraints.
