17F half-life mesurement at the NSL
Published: February 2016 Brodeur
The half-life of 17F was measured using a ß-counting station at the NSL. The measured value is in agreement with several past measurements and represents one of the most precise measurements to date. The uncertainty on the world’s half-life average is still greater than the Q-value. This stems from the large scatter in the world’s data. More independent measurements in the future would be necessary to mitigate the situation. Finally, the inclusion of 17F for testing the CVC and for the extraction of the Vud matrix element will require the measurement of the mixing ratio r. A dedicated Paul trap is currently being planned to perform such a measurement at the NSL. Learn more
