Abstract
The -decay half-lives of 38 neutron-rich isotopes from to have been measured; the half-lives of , , , , , , and are reported here. The results when compared with previous standard models indicate an overestimation in the predicted half-lives by a factor of 2 or more in the region. A revised model based on the second generation gross theory of decay better predicts the measured half-lives and suggests a more rapid flow of the rapid neutron-capture process (-matter flow) through this region than previously predicted.
