A FRAGMENT SEPARATOR AT LBL FOR THE BETA-NMR EXPERIMENT

[摘要] The Beam 44 fragment separator was built at the Bevalac of LBL for NMR studies of beta emitting nuclei. K-37, Ca-39, and Ti-43 fragments originating from Ca-40 and Ti-46 primary beams were separated by the separator for NMR studies on these nuclei. Nuclear spin polarization was created in Ca-39 and Ti-43 using the tilted foil technique (TFT), and the magnetic moment of Ti-43 was deduced. Fragment polarization was measured for K-37 and Ca-39 emitted to finite deflection angles. The Beam 44 fragment separator in combination with a proper polarization technique, such as TFT or fragment polarization, has been very effective for such NMR studies.
