Precision mass measurements around Mo rule out ZrNb cycle formation in the rapid proton-capture process at type I X-ray bursts
S. Kimura, M. Wada, C. Y. Fu +27
The rapid proton-capture (-) process is one of the primary, explosive thermonuclear burning processes that drive type I X-ray bursts. A possible termination of the -process…
Comprehensive mass measurement study of Cf fission fragments with MRTOF-MS and detailed study of masses of neutron-rich Ce isotopes
Sota Kimura, Michiharu Wada, Hiromitsu Haba +7
We report the mass measurements of neutron-rich isotopes produced via spontaneous fission of Cf using a multi-reflection time-of-flight mass spectrograph. The mass of ${}…
Design report of the KISS-II facility for exploring the origin of uranium
Takamichi Aoki, Yoshikazu Hirayama, Hironobu Ishiyama +14
One of the critical longstanding issues in nuclear physics is the origin of the heavy elements such as platinum and uranium. The r-process hypothesis is generally supported as the…
A new study of the and shell gap for Ti and V by the first high-precision MRTOF mass measurements at BigRIPS-SLOWRI
S. Iimura, M. Rosenbusch, A. Takamine +34
The atomic masses of Sc, Ti, and V have been determined using the high-precision multi-reflection time-of-flight technique. The radioisotopes have been p…
The new MRTOF mass spectrograph following the ZeroDegree spectrometer at RIKEN's RIBF facility
M. Rosenbusch, M. Wada, S. Chen +23
A newly assembled multi-reflection time-of-flight mass spectrograph (MRTOF-MS) at RIKEN's RIBF facility became operational for the first time in spring 2020; further modifications…
Alpha-decay-correlated mass measurement of 206,207Ra using an -TOF detector equipped MRTOF-MS system
T. Niwase, M. Wada, P Schury +25
The atomic masses of the isotopes Ra have been measured via decay-correlated mass spectroscopy using a multi-reflection time-of-flight mass spectrograph equipped with a…
First high-precision direct determination of the atomic mass of a superheavy nuclide
P. Schury, T. Niwase, M. Wada +25
We present the first direct measurement of the atomic mass of a superheavy nuclide. Atoms of Db (=105) were produced online at the RIKEN Nishina Center for Accelerator-B…
Development of a resonant laser ionization gas cell for high-energy, short-lived nuclei
T. Sonoda, M. Wada, H. Tomita +21
A new laser ion source configuration based on resonant photoionization in a gas cell has been developed at RIBF RIKEN. This system is intended for the future PArasitic RI-beam prod…
