Free-ion hyperfine fields and magnetic-moment measurements on radioactive beams

Abstract

The recoil in vacuum (RIV) technique for magnetic-moment measurements on radioactive beams is discussed with examples from the 132Sn region. Attention then turns to recoil in vacuum and the free-ion hyperfine fields of Se and Ge ions leaving carbon foils with velocities of about 5% of the speed of light. These notionally similar ions show unexpected differences which must stem from differences in their atomic structure. Show more
