Abstract

We performed a precision missing-mass spectroscopy experiment of the deeply bound pionic states in a 121Sn atom using the (d,3He) reaction near the π− emission threshold. The experiment serves as a pilot experiment for our new ‘pionic atom factory project’ at RIBF, which aims at precision spectroscopy of the energy spectrum of the pionic atom of isotopes and isotones. The result of the pilot experiment demonstrated the potentiality of BigRIPS and of the RIBF facilities for the project. The current status of the analysis is reported.

Abstract

We have performed an inclusive spectroscopy of 122Sn(d, 3He) reaction near the pion emission threshold at an incident energy of Td = 250 MeV/nucleon. The first experiment aims as devloping the high precision spectroscopy of pionic atoms at the RI beam factory (RIBF) of RIKEN, which leads to a new project, pionic Atom Factory project (piAF) to measure pionic atoms for a wide range of elements. We report the analysis status of the pilot experiment.

Abstract

NeuLAND (New Large-Area Neutron Detector) is the next-generation neutron detector for the R3B (Reactions with Relativistic Radioactive Beams) experiment at FAIR (Facility for Antiproton and Ion Research). NeuLAND detects neutrons with energies from 100 to 1000 MeV, featuring a high detection efficiency, a high spatial and time resolution, and a large multi-neutron reconstruction efficiency. This is achieved by a highly granular design of organic scintillators: 3000 individual submodules with a size of 5 × 5 × 250 cm3 are arranged in 30 double planes with 100 submodules each, providing an active area of 250 × 250 cm2 and a total depth of 3 m. The spatial resolution due to the granularity together with a time resolution of 150 ps ensures high-resolution capabilities. In conjunction with calorimetric properties, a multi-neutron reconstruction efficiency of 50% to 70% for four-neutron events will be achieved, depending on both the emission scenario and the boundary conditions allowed for the reconstruction method. We present in this paper the final design of the detector as well as results from test measurements and simulations on which this design is based.

Abstract

We have measured the energy spectrum of pionic Sn atoms by missing-mass spectroscopy of the Sn( d, He) reaction near the π emission threshold. The measurement serves as a pilot experiment for high precision systematic spectroscopy of deeply bound pionic atoms in a new pionic Atom Factory project (piAF) at the RI beam factory (RIBF) of RIKEN. The status of the analysis is reported. [ABSTRACT FROM AUTHOR]

Abstract

Possible directions of nuclear spin-isospin response studies are discussed. They includes i) light-ion induced charge exchange reaction studies in inverse-kinematics experiments with RI-beams, ii) studies with heavy-ion stable-beam induced charge exchange reactions, and iii) studies with RI-beam induced charge exchange reactions. Among them, RI-beam induced charge exchange reactions have unique properties which are missing in stable-beam induced reactions and can be used to reveal new aspects of spin-isospin responses in nuclei. Several experiments have been done and are planned with the SHARAQ spectrometer at RI Beam Factory, by utilizing the unique properties.

Abstract

The 116Cd(p,n) experiment at 300 MeV has been performed for deducing the Gamow-Teller (GT) transition strengths B(GT−) in 116In. For the transition to the ground state, the B(GT − ) value of 0.26 ± 0.02 is obtained. From this B(GT−) value and the B(GT+) value by a beta-decay experiment, the contribution of the intermediate ground state of 116In to the nuclear matrix element is deduced to be 0.070 ± 0.003. The B(GT−) value obtained herein is a factor of 8 less than that obtained from a previous (3He,t) measurement. This discrepancy, as well as differences in the distribution of low energy GT strength, and the width and peak energy of the GT giant resonance may be explained if the target used in the (3He,t) measurement is a Cd target with natural abundance.
