被引用回数：0 パーセンタイル：0.00(Physics, Nuclear)From 2020 to 2021, as part of the HiCARI project, high-resolution in-beam -ray spectroscopy experiments were conducted at the Radioactive Isotope Beam Factory. Using a collaboratively constructed array of 12 composite Ge detector systems, excitation state half-lives through Doppler-shifted spectroscopy were measured to investigate various physical phenomena. Specifically, we analyzed the Doppler-shifted line shapes of specific spin transitions and decays in In, Sn, and Te, characterizing the array and establishing reliable analytical methods. The obtained half-lifes were compared with existing experimental results and theoretical calculations.

被引用回数：8 パーセンタイル：74.79(Physics, Multidisciplinary)At the RIBF facility in RIKEN, the half-lives of the 6
and 8 excited states of semi-magic nucleus Cd were measured, and the B(E2) transition matrix elements of the corresponding transitions were deduced. This information was used to determine the effective proton charges in Cd. By comparing these new results with the effective charges deduced from a previous measurement of 
Cd, the effective charges near doubly magic 
Sn and 
Sn could be compared for the first time. This revealed an unexpected large decrease of the isovector effective charges due to the increasing number of neutrons. This information is very important for state-of-the-art large scale shell model calculations.

被引用回数：6 パーセンタイル：65.02(Instruments & Instrumentation)The ISOLDE Scientific Infrastructure at CERN offers a unique range of post-accelerated radioactive beams. The scientific program can be improved with the Isolde Superconducting Recoil Separator (ISRS), an innovative spectrometer able to deliver unprecedented (A, Z) resolution. In this paper we present an overview of the physics and ongoing technical developments.
