Differential cross sections and analyzing powers have been measured for (p, d) reactions on 1p,2s,1d,1f,2p,1g and 2d shell nuclei with 65 MeV polarized protons. The analyzing powers clearly show a j‐dependence which depends on the numbers of nodes in the radial wave function of the neutron. The shapes of the angular distributions of the analyzing powers can be classified into five types for simple neutron pickup reactions from these shells. The pickup from the 1p1/2 shell is singular. The analyzing powers for the 1p1/2 shell neutron pickup can be reproduced by DWBA calculations only when large values of the radius and diffuseness parameters are used in the bound state potential.

The angular distributions of cross sections and analyzing powers for proton inelastic scattering leading to the 11.58 MeV and 14.36 MeV states in 28Si and the 15.15 MeV state in 24Mg have been measured with 65 MeV polarized proton beam using the spectrograph RAIDEN. Preliminary microscopic DWBA calculations including exchange process have been performed. The results are discussed.

This paper proposes a Reduction-based Parallel Inference Machine : PIM-R and describes the architecture and its evaluation using two kinds of software simulators. Target languages of PIM-R are Prolog and Concurrent Prolog. PIM-R executes Prolog programs in OR parallel and Concurrent Prolog programs in AND parallel. The simulation results show that PIM-R is able to exploit the parallelism in Prolog and Concurrent Prolog programs.

The $\ensuremath{\gamma}n\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}n$ reaction on $^{12}\mathrm{C}$ has been studied by measuring both ${K}^{+}$ and ${K}^{\ensuremath{-}}$ at forward angles. A sharp baryon resonance peak was observed at $1.54\ifmmode\pm\else\textpm\fi{}0.01\text{ }\text{ }\mathrm{G}\mathrm{e}\mathrm{V}/{c}^{2}$ with a width smaller than $25\text{ }\text{ }\mathrm{M}\mathrm{e}\mathrm{V}/{c}^{2}$ and a Gaussian significance of $4.6\ensuremath{\sigma}$. The strangeness quantum number ($S$) of the baryon resonance is $+1$. It can be interpreted as a molecular meson-baryon resonance or alternatively as an exotic five-quark state ($uudd\overline{s}$) that decays into a ${K}^{+}$ and a neutron. The resonance is consistent with the lowest member of an antidecuplet of baryons predicted by the chiral soliton model.

The cross sections was measured for coherent double neutral-pion photoproduction on the deuteron using the tagged photon beams from the 0.9 and 1.2 GeV primary electron beams at the Research Center for Electron Photon Science, Tohoku University, Japan. The four-momenta of the four photons from the two $\pi^0$ decays and deuteron are measured with the FOREST detector, and the $\gamma d\to \pi^0\pi^0d$ reaction was identified using 6-constraint kinematic fit (energy and three-momentum conservation, and two $\pi^0$ masses). The total cross section is found to be $18.4\pm 9.2$~nb for the $d^*(2380)$ dibaryon resonance at $W_{\gamma d}=2.37$~GeV, which is a candidate of the isoscalar $\Delta \Delta $ quasi-bound state ${\cal D}_{03}$, in the $\gamma d \to \pi^0\pi^0 d$ reaction. The measured excitation function is consistent with the existing theoretical calculation for this reaction. At high incident energies, $\pi^0d$ invariant-mass distributions show a peak at approximately 2.15 GeV, which can be attributed to a $N\Delta$ quasi-bound state ${\cal D}_{12}$. In this contribution, the properties (mass, width, and decay angular distribution) of this peak is presented.

In order to investigate how the electronic structure of Cu atoms varies when superconductivity is suppressed by metal doping, d.c. susceptibility, electrical resistivity and lattice parameters are measured for YBa 2 (Cu 0.99−x Fe 0.01 Al x ) 3 O 7−z . It was found that the effective moment per Fe calculated from Curie constant decreases from 5.0 to 3.8 μ B with increase of Al contents up to x=0.08. These results indicate that there exists local antiferromagnetic coupling between Fe and induced moments on the nearest neighbour Cu atoms without long range order even in superconducting state.

In order to investigate magnetic interaction and its effect on superconductivity in GdBa 2 (Cu 1−x Fe x ) 3 O 7−y , critical temperature Tc, lattice parameters, d.c. susceptivility, Gd-ESR and Neel temperature T N are measured. We found tha ESR linewidth δH pp increases but T N decreases from 2.3 K to 2.0 K with increasing x up to 0.19. This indicates that there exists some magnetic interaction between Gd and Fe atoms even in superconducting state.

The nonresonant multiphoton ionization of rare gases has been studied by means of XeCl, KrF and ArF excimer lasers. In the course of this study, it was observed that in the cases of the XeCl and KrF lasers, the ionization intensities of Xe gas were stronger than those of Kr gas, but in the case of the ArF laser, the former was weaker than the latter. This result is interpreted as an effect of laser wavelength.
