Description

In order to investigate the possible influence of metallic environment on the alpha decay process, we have measured the 147Sm activities in the hosts of metal samarium and Sm2O3. The 147Sm half-life was found to be (1.06±0.01) x 1011 y in metal samarium and (1.07±0.01) x 1011 y in Sm2O3, respectively. No significant change has been observed within the experimental uncertainty. The absolute half-life presented here is consistent with the recommended value. (orig.)
