Description
I will present recent research activities in Japan on low-energy electron scattering in nuclear physics. These include electron scattering with beam energies of Eₑ = 10–60 MeV at the ULQ2 facility in Sendai, and structure studies of short-lived exotic nuclei at the SCRIT facility at RIKEN.
[ULQ2 (Ultra-Low Q²)]
Electron scattering from the proton in the extremely low momentum-transfer region is essential for a precise determination of the proton charge radius. To this end, we have constructed the ULQ2 facility at Tohoku University in Sendai, where one can conduct extremely low-energy electron scattering, Eₑ = 10–60 MeV.
Recently, we have completed a series of low-energy electron-scattering measurements on the proton (and the deuteron), covering the lowest-ever momentum transfer. In this talk, I will present details of the ULQ2 facility, the current status of this project, and several new research programs that have recently been initiated.
[SCRIT (Self-Confining Radioactive Ion Target) ]
We have achieved a groundbreaking milestone: the world’s first electron scattering experiment on an online-produced radioactive isotope, performed at the SCRIT electron-scattering facility of RIKEN RIBF in Japan. I will briefly introduce the SCRIT facility, highlight recent achievements, and outline the wide range of new research opportunities now possible at this unique facility.
