Scientific paper
The half-life of Al-26 has been redetermined because of suggestions of an error in the accepted value based on its use in calculating Ne-21 production rates from cosmic rays in meteorites. Two solutions of Al-26 were analyzed for the specific radioactivity and mass spectrometric determination of the Al-26 concentration. The half-life obtained for Al-26 was 705,000 years + or - 3.4 percent. This is identical to the accepted value of 716,000 years and indicates that problems with the Ne-21 production are not due to an erroneous half-life.
