Half life of 26Al

Creators

Description

The half-life of 26Al has been redetermined because of suggestions of an error in the accepted value based on its use in calculating 21Ne production rates from cosmic rays in meteorites. Two solutions of 26Al were analyzed for the specific radioactivity and mass spectrometric determination of the 26Al concentration. The half-life obtained for 26Al was 7.05 x 105 years +- 3.7% at the two sigma level. This is identical to the accepted value of 7.16 x 105 years and indicates that problems with the 21Ne production rate is not due to an erroneous half-life
