Abstract

The

{}^{238}{Pu}

half-life was measured at 87.71 ± 0.03 yr by observing the

{}^{238}{Pu}

α

-particle activity formed from the

α

decay of

{}^{242}{Cm}

. Samples of

{}^{242}{Cm}

were counted three times in a 262 day interval, leading to a

{}^{242}{Cm}

half-life of 162.76 ± 0.04 days. Both values agree well with measurements made by other methods.
