Matter radius of the doubly-magic ^56 Ni measured in a storage ring
The European Physical Journal A(2023)
摘要
The matter radius of the doubly magic ^56 Ni was extracted from a measurement of the differential cross section by employing, for the first time, elastic proton scattering in inverse kinematics with a radioactive beam at E_kin=390.2 MeV/nucleon circulating in a storage ring and passing an internal hydrogen gas-jet target with a revolution frequency of around 2 MHz. The novel experimental scheme is based on UHV-compatible Si detectors operated as active vacuum windows, which were implemented in the ESR storage ring at GSI. A matter radius ^1/2=3.74^+0.03_-0.06 fm was extracted for the doubly-magic self-conjugate nucleus ^56 Ni.
