Physicists Reinvestigate Nuclear Excitation by Electron Capture Using Isomer Beam

To reinvestigate isomer depletion, researchers at IMP and their collaborators used an isomer beam to avoid contamination from the heavy gamma background. The significantly increased experimental sensitivity indicates that it is a promising approach for studying isomer depletion. A “dark” environment was created at the Radioactive Ion Beam Line in Lanzhou (RIBLL), China, to look for a faint flash of light as evidence of isomer depletion. Such depletion is required to harn...
