Precision masses of neutron-rich platinum and gold nuclei reveal enhanced shell strength below doubly-magic Pb
David Freire-Fernández, Rui-Jiu Chen, Usama Ahmed +63
The heaviest stable nuclei in the universe owe their existence to quantum shell structure, the grouping of protons and neutrons into discrete energy levels separated by gaps. The l…
Isochronous mass spectrometry at the RIKEN Rare-RI Ring facility
D. Nagae, S. Omika, Y. Abe +28
A dedicated isochronous storage ring, named the Rare-RI Ring, was constructed at the RI Beam Factory of RIKEN, aiming at precision mass measurements of nuclei located in uncharted…
First application of mass measurement with the Rare-RI Ring reveals the solar r-process abundance trend at A=122 and A=123
H. F. Li, S. Naimi, T. M. Sprouse +41
The Rare-RI Ring (R3) is a recently commissioned cyclotron-like storage ring mass spectrometer dedicated to mass measurements of exotic nuclei far from stability at Radioactive Iso…
Charge-changing cross sections for Ca and effect of charged-particle evaporation induced by neutron removal reaction
M. Tanaka, M. Takechi, A. Homma +65
Charge-changing cross sections for Ca on a carbon target at around 280~MeV/nucleon have been measured. The measured values diffe…
Development and operation of an electrostatic time-of-flight detector for the Rare RI storage Ring
D. Nagae, Y. Abe, S. Okada +28
An electrostatic time-of-flight detector named E-MCP has been developed for quick diagnostics of circulating beam and timing measurement in mass spectrometry at the Rare-RI Ring in…
Swelling of doubly magic Ca core in Ca isotopes beyond
M. Tanaka, M. Takechi, A. Homma +67
Interaction cross sections for Ca on a carbon target at 280 MeV/nucleon have been measured for the first time. The neutron number dependence of derived root-mean…
Proton-proton correlations in distinguishing the two-proton emission mechanism of Al and Mg
D. Q. Fang, Y. G. Ma, X. Y. Sun +43
The proton-proton momentum correlation functions () for kinematically complete decay channels of Al p + p + Na and Mg p…
Different mechanism of two-proton emission from proton-rich nuclei Al and Mg
Y. G. Ma, D. Q. Fang, X. Y. Sun +43
Two-proton relative momentum () and opening angle () distributions from the three-body decay of two excited proton-rich nuclei, namely Al p + p…
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…
Nuclear structure of 30S and its implications for nucleosynthesis in classical novae
K. Setoodehnia, A. A. Chen, D. Kahl +29
The uncertainty in the 29P(p,gamma)30S reaction rate over the temperature range of 0.1 - 1.3 GK was previously determined to span ~4 orders of magnitude due to the uncertain locati…
