摘要：

Samarium-145 nuclei were oriented at low temperatures in neodymium ethylsulfate (NES) and cerium magnesium nitrate (CMN) lattices. From the temperature-dependent angular distribution of the 61-keV γ ray in Pm145, a magnetic moment μ=0.92±0.06μN was deduced for the ground state of Sm145. The ratio of attenuation coefficients in the 61-keV state of Pm145 in the two lattices was found to be G2(CMN)G2(NES)=+0.44(10). Evidence is presented which indicates that temperature gradients in CMN can lead to erroneously low values for magnetic moments. © 1969 The American Physical Society.
