184" CYCLOTRON
HALF-LIFE MEASUREMENTS ON DEE

By Alice Dodson

Experiment done by: W. Stephan, W. Chupp, W. Grimshaw, A. Reyenga, F. Yeater,
A. Oliver, R. Dufour, J. Vale, R. Watt, and L. Houser



INTRODUCTION


These experiments were performed to determine the half-life of the active portion of
the Dee.


EXPERIMENTAL SETUP


Curve Number 1 measurements were made on Zeus ML 41345 on February 10 and 11,
1947. Curve Number 2 measurements were made on Zeus ML 41394 on February 18, 1947.
Measurements were started about 7 hours after operation ceased. See sketch for location
of Zeus (Figure 1).


RESULTS


The half-life of this material is approximately 7 hours. (See graph.)
