Nuclear orientation of ²⁰⁶Bi in nickel

Abstract

A study of the 206Pb decay was performed by nuclear orientation of 206Bi nuclei in a nickel host at low temperatures. The hyperfine field of 206Bi/Ni was determined to be 400 ± 34 kG, with 65% of the bismuth nuclei occupying lattice sites. Mixing ratios were determined for several transitions in the 206Pb decay. Attenuation coefficients due to reorientation effects in the isomeric state at 2200 keV excitation in 206Pb were measured.A discussion of the reasons for fractional occupation of lattice sites by the bismuth nuclei is given.
