The two-arm spectrometer, Grand Raiden and Large Acceptance Spectrometer (LAS) equipped with a high resolution beam line is a powerful tool of nuclear physics studies. Grand Raiden spectrometer has high resolution (D/M=37,000) by applying complete dispersion matching including both lateral and angular dispersion and focus matching, while LAS has large acceptance (20 msr). The Focal Plane Polarimeter (FPP) for Grand Raiden can analyze the polarization of protons with an efficiency of about 3% and an effective analyzing power of about 40%. It can measure the longitudinal component of the polarization vector with DSR magnet. For more technial information, please refere to the following web page and publication.

The basic specification of the Grand Raiden Spectrograph is listed in the table. There are two vertical drift chambers (effective length 1.2 m ) for general use as the focal plane position counters of the spectrometer. The position and angular resolution obtained from ray-tracing are 0.2 mm and 2.0 mr, respectively. The Focal Plane Polarimeter (FPP) can analyze the polarization of protons with an efficiency of about 3% and an effective analyzing power of about 40%. The whole system is mounted on a rotatable table and angular distributions of scattered particles from -5 deg to 90 deg can be measured. In the scattering chamber there are three remote driving systems, target (up and down), a turntable with Faraday cup, and one general purpose turntable. F |

The basic specification of the Grand Raiden Spectrograph is listed in the table. The focal plane counter system consists of two vertical drift chambers (effective length: 1.7 m, effective height: 35 cm ) for ray-tracing and two planes of plastic scintillators for the trigger (200cm x 45cm, 6 mm thickness). In addition, twelve segmented scintillators (hodoscope) are available for the measurement of 2He or other two particles in coincidence. It is possible to measure and analyze with a momentum resolution of 5x10-4 (including momentum width of beam), and angular resolution (FWHM) of 2 mr horizontally and 30 mr vertically. In the zero-degree measurements,if the momentum of the measured particle is about half of the incident beam momentum, we can transport the incident beam through the spectrograph and stop in an external beam dump. |

Evidence of Tensor Interactions in 16O
|
The tensor interactions are some of the most important nuclear interactions acting between a neutron and a proton in an atomic nucleus. Despite the importance, experiment evidences are scarce and limited to nuclei with masses equal to or lighter than the alpha particle. In a recent experiment measuring the one-neutron transfer (p,d) reaction at large momentum transfer on an 16O target using the RCNP Grand Raiden spectrometer, we observed a possible evidence on the effect of the tensor interactions in the 16O nucleus [1]. The (p,d) cross sections populating the 5/2+ and/or 1/2+ excited state in 15O were found to be increased compared to the cross sections populating the ground 1/2- state with increased momentum transfer. Because (i) the tensor interactions can generate proton-neutron pairs with large relative momentum, and (ii) the population of the 5/2+ and/or 1/2+ excited state via the direct (p,d) reaction is only possible if the ground-state of 16O has mixed configurations which may be attributed to the tensor interactions (see Fig.), the observation of large components of high-momentum neutrons in the ground-state of 16O indicates possible evidence on the tensor interactions. Referrence [1] H. J. Ong, I. Tanihata, A. Tamii et al., Phys. Lett. B725, 277 (2013). |

Pygmy Dipole Resonance:
|
Concentration of electric dipole (E1) strength in the vicinity of the neutron threshold has recently been found in several stable and unstable heavy nuclei. The strength is called the low-energy dipole strength or the Pygmy Dipole Resonance (PDR) in relation to the theoretical predictions of the dipole oscillation of the neutron skin against the isospin-saturated core. The PDR strength has been studied by applying the proton inelastic scattering at forward angles employing the high-resolution spectrometer Grand Raiden. The PDR strength in 90Zr has been clearly separated from the spin-M1 contribution (Fig. ) [1]. Concentration of the skin-oscillation type transition density is also found in 208Pb [2].

Gamow-Teller Strength and the double-beta decay matrix element
|
The Gamow-Teller strength distribution has been determined by (3He,t) charge-exchange rations on 136Xe [1], 71Ge [2], 76Ge [3], 128,130Te [4], 100Mo [5] and 96Zr. The data are important to study the double-beta decay nuclear matrix-elements as well as the charged-current reaction cross sections of neutrino detectors. Referrence [1] P.
