Abstract
The magnetic hyperfine field of Ba in ferromagnetic Ni has been measured by time differential perturbed angular distribution technique using the 13 ns 10+ isomeric state in 132Ba as probe which was populated in the reaction 12C(124Sn, 4n) 132Ba at beam energy of 60 MeV. The hyperfine field extracted from the observed Larmor precession frequency comes out to be −84(5) kG. Our experimental results show good agreement with theoretical calculations performed within local density approximation of the density functional theory. The hyperfine field data presented here would be useful towards accurate determination of g-factor in other high spin states in Ba isotopes.
