Accurately accounting for effects on times-of-flight caused by finite field-transition times during the ejection of ions from a storage trap: A study for TOF and MRTOF mass spectrometry
M. Rosenbusch, P. Schury, M. Wada +3
In applied forms of time-of-flight mass spectrometry utilizing ion storage devices prior to an analysis device, a non instantaneous electric ejection pulse applied in the region of…
Quantum critical behavior in heavily doped LaFeAsOH pnictide superconductors analyzed using nuclear magnetic resonance
R. Sakurai, N. Fujiwara, N. Kawaguchi +5
We studied the quantum critical behavior of the second antiferromagnetic (AF) phase in the heavily electron-doped high- pnictide, LaFeAsOH by using As and $…
Experimental evidence of enhancement without the influence of spin fluctuations: NMR study on LaFeAsO_{1-x}H_x under a pressure of 3.0 GPa
N. Kawaguchi, N. Fujiwara, S. Iimura +2
The electron-doped high-transition-temperature (T_c) iron-based pnictide superconductor LaFeAsO_{1-x}H_x has a unique phase diagram: superconducting (SC) double domes are sandwiche…
Detection of antiferromagnetic ordering in heavily doped LaFeAsO1-xHx pnictide superconductors using nuclear-magnetic-resonance techniques
N. Fujiwara, S. Tsutsumi, S. Iimura +4
We studied double superconducting (SC) domes in LaFeAsO1-xHx by using 75As- and 1H-nuclear magnetic resonance techniques, and unexpectedly discovered that a new antiferromagnetic (…
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…
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…
