    Abstract

    Previously, we developed an α-TOF detector for correlated measurements of atomic masses and decay properties of radioactive isotopes using a multi-reflection time-of-flight mass spectrograph, and successfully demonstrated α-decay-correlated mass measurements of heavy and superheavy nuclides. In this work, we develop a β-TOF detector, an improvement upon the α-TOF detector, to extend this technology to β-decaying nuclides. Online commissioning with 81Ga yielded a measured half-life of 1.44(31) s, in agreement with the previous literature, and confirmed the efficiency of detecting a decay-correlated event to be consistent with the solid angle limitation.

    The atomic masses of the isotopes have been measured via decay-correlated mass spectroscopy using a multireflection time-of-flight mass spectrograph equipped with an -TOF detector. The Ra isotopes were produced as fusion-evaporation products in the reaction system and delivered by the gas-filled recoil ion separator GARIS-II at RIKEN. The -TOF detector provides for high-accuracy mass measurements by correlating time-of-flight signals with subsequent -decay events. The masses of and were directly measured using a multireflection time-of-flight mass spectrograph equipped with an -TOF detector. The mass excesses of and the excitation energy of were determined to be , and keV, respectively. The -decay branching ratio of , was directly determined from decay-correlated time-of-flight signals, and the reduced width of was calculated to be keV from the branching ratio. The spin-parity of was confirmed to be from decay correlated mass measurement results.

     More details

    Language:English   Publishing type:Research paper (scientific journal)  

    We have developed a novel detector, referred to as an "alpha-TOF detector", for correlated measurements of atomic masses and decay properties of low-yield, short-lived radioactive isotopes using a multi-reflection time-of-flight mass spectrograph. By correlating measured time-of-flight signals with decay events, it will be possible to suppress background events and obtain accurate, high-precision mass and half-life values even in cases of very low event rates. An offline test of the alpha-TOF detector has shown that the time-of-flight detection efficiency for 5.48 MeV alpha-rays is more than 90&#37; and yields a time resolution of 250.6(68) ps and an alpha-energy resolution of 141.1(9) keV. Using a two-dimensional spectrum of the correlated alpha-ray energy and time-of-flight, the alpha-rays from mixed alpha sources could be resolved. Subsequent testing using alpha-emitting nuclei extracted offline from a gas cell provide verification of the alpha-ray based characterization.
