Chiral symmetry restoration at high matter density observed in pionic atoms
Takahiro Nishi, Kenta Itahashi, DeukSoon Ahn +45
Modern theories of physics tell that the vacuum is not an empty space. Hidden in the vacuum is a structure of anti-quarks and quarks . The and pair has t…
Parity-transfer reaction as a selective probe of isovector states in nuclei
M. Dozono, M. Ichimura, S. Michimasa +34
We demonstrate that the parity-transfer reaction provides a selective probe of isovector excitations in nuclei. This reactio…
Spectroscopy of nuclei around Sn populated via two-neutron knockout reactions
A. Corsi, A. Obertelli, P. Doornenbal +27
We report on the in-beam gamma spectroscopy of Sn and Cd produced via two-neutron removal from carbon and CH targets at about 150 MeV/nucleon beam energy. New t…
Structure of 55Sc and development of the N=34 subshell closure
D. Steppenbeck, S. Takeuchi, N. Aoi +22
The low-lying structure of Sc has been investigated using in-beam -ray spectroscopy with the Be(Ti,Sc+) one-proton removal and Be(S…
Separated flow operation of the SHARAQ spectrometer for in-flight proton decay experiments
M. Dozono, T. Uesaka, S. Michimasa +6
New operation mode, "separated flow mode", has been developed for in-flight proton decay experiments with the SHARAQ spectrometer. In the separated flow mode, the protons and the h…
Neutron occupancy of the 0d5/2 orbital and the N=16 shell closure in 24O
K. Tshoo, Y. Satou, C. A. Bertulani +34
One-neutron knockout from 24O leading to the first excited state in 23O has been measured for a proton target at a beam energy of 62 MeV/nucleon. The decay energy spectrum of the n…
Beam energy dependence of charged pion ratio in Si + In reactions
M. Sako, T. Murakami, Y. Nakai +10
The double differential cross sections for In(Si, ) reactions are measured at 400, 600, and 800 MeV/nucleon. Both and are found to be emitted is…
Collectivity evolution in the neutron-rich Pd isotopes towards the N=82 shell closure
H. Wang, N. Aoi, S. Takeuchi +29
The neutron-rich, even-even 122,124,126Pd isotopes has been studied via in-beam gamma-ray spectroscopy at the RIKEN Radioactive Isotope Beam Factory. Excited states at 499(9), 590(…
Intermediate-energy Coulomb excitation of 104Sn: Moderate E2 strength decrease approaching 100Sn
P. Doornenbal, S. Takeuchi, N. Aoi +25
The reduced transition probability B(E2) of the first excited 2+ state in the nucleus 104Sn was measured via Coulomb excitation in inverse kinematics at intermediate energies. A va…
Observation of new microsecond isomers among fission products of 345 MeV/nucleon 238U
D. Kameda, T. Kubo, T. Ohnishi +56
A search for isomeric gamma-decays among fission fragments from 345 MeV/nucleon 238U has been performed at the RIKEN Nishina Center RI Beam Factory. Fission fragments were selected…
Hindered proton collectivity in 28S: Possible magic number at Z=16
Y. Togano, Y. Yamada, N. Iwasa +34
The reduced transition probability B(E2;0 ->2+) for 28S was obtained experimentally using Coulomb excitation at 53 MeV/nucleon. The resultant B(E2) value 181(31) e2fm4 is smaller t…
The N = 16 spherical shell closure in 24O
K. Tshoo, Y. Satou, H. Bhang +32
The unbound excited states of the neutron drip-line isotope 24O have been investigated via the 24O(p,p')23O+n reaction in inverse kinematics at a beam energy of 62 MeV/nucleon. The…
