Abstract

Radioactive191Pt(3/2−) alloyed to iron has been oriented at low temperature in a dilution refrigerator. The resonance absorption spectrum of the 82.4 keV transition of the polarized split source has been registered at high (≈ 1 K) and low (≤ 15 mK) temperatures. From the high temperature spectrum δ (E2/M1; 82.4) < 0 is established. From the positive-to-negative speed asymmetry of the low tempe rature spectrum we determined μ[191-Pt(g.s.)] > 0. This result is in agreement with deformed Hartree-Fock calculation predictions.
