Lifetimes ofN=ZnucleiAs66andBr70

Abstract
We have utilized a rapid-transport target system together with a β-ray range telescope to remeasure the half-lives of the N=Z, odd-odd nuclei As66 and Br70. We find they are 95.77±0.28 ms and 78.54±0.59 ms, respectively. The As66 result is in good agreement with the previous study, while the Br70 measurement differs somewhat from the previous result.
