Alpha decay half-life of 147Sm in metal samarium and Sm2O3

. In order to investigate the possible influence of metallic environment on the alpha decay process, we have measured the 147 Sm activities in the hosts of metal samarium and Sm 2 O 3 . The 147 Sm half-life was found to be (1.06±0.01)×10 11 y in metal samarium and (1.07±0.01)×10 11 y in Sm 2 O 3 , r...

Zusammenfassung:	. In order to investigate the possible influence of metallic environment on the alpha decay process, we have measured the 147 Sm activities in the hosts of metal samarium and Sm 2 O 3 . The 147 Sm half-life was found to be (1.06±0.01)×10 11 y in metal samarium and (1.07±0.01)×10 11 y in Sm 2 O 3 , respectively. No significant change has been observed within the experimental uncertainty. The absolute half-life presented here is consistent with the recommended value.
