被引用回数：0 パーセンタイル：0.00(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：3 パーセンタイル：46.61(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.

Developments in advanced manufacturing (AM) are occurring faster than the ability to introduce new materials and methods into design codes. Qualifying new AM technologies for use with nuclear design codes can be a long and complex process. The Generation IV International Forum (GIF) Advanced Manufacturing Materials Engineering Task Force (AMME-TF), focuses on how collaborative AM R&D could be used to decrease time to deployment of Gen-IV reactors. This paper provides a critical review of 2019 and 2021 surveys sampling nuclear reactor vendors, supply chain specialists, regulators, and other experts in GIF member countries. Both surveys confirmed that many AM technologies were considered opportunities by potential end users, although 90% of respondents identified the creation and approval of codes and standards as the greatest obstacle to their adoption. Industry prioritization on AM technologies, components and materials changed significantly during the three-year timespan. Additionally, the paper summarizes a 2021 modeling & simulation workshop that developed ideas on how to accelerate the qualification of AM and synthesizes the survey results and workshop conclusions into a review of critical research gaps and paths to address these gaps, particularly through international collaboration.
