On-line orientation of bromine isotopes
Hyperfine Interactions 75:1-4 (1992) 431-438
Abstract:
Assignments for the principal Nilsson configuration in light β+-decaying bromine isotopes were proposed in a contribution to the OLNO-1 conference. These assignments were made on the basis of magnetic moments derived from the temperature dependence of anisotropies in daughter Se isotopes observed in the DOLIS-COLD facility at Daresbury. Anisotropy measurements have since been extended to a lower base temperature in74 mBr and72 gBr decay, leading to more stringent limits on the ground state moment of72Br. The proposed π[312]3/2 configuration for75Br has also now been confirmed by a measurement of the sign of its magnetic moment. This was done by observing the β-asymmetry in75Br decay using high purity Si detectors mounted within the dilution refrigerator. © 1992 J.C.

Abstract:
A low temperature nuclear orientation study has been performed on Fr in Fe. Anisotropy measurements of both gamma rays and alpha particles have been done. The best value for the hyperfine field, obtained in the gamma-ray experiment, is 129.7(40) T. The results from the alpha-particle experiment support this value. The value is a factor of 2 larger than measured earlier; at present there is no good explanation for this discrepancy. A lower limit of 37% and an upper limit of 45% of Fr in high field site can be set. © 1992.Hyperfine field and fraction in high field site for implanted 221FrFe
