Abstract
The threshold energy of the reaction has been measured using solid targets and has been found to be 7008.52(12) keV, with a 1 V standard as reference. This is in agreement with, but more precise than, the accepted value. The average gives a value for the superallowed positron decay of 6044.34(12) keV and an ft value of 3049.4(21) s. To improve this last, the discord in the measured halflives should be resolved.
