A half-life of 2.2 {+-} 0.2 s has been deduced for the ground-state {beta} decay of {sup 84}Mo, more than 1{sigma} shorter than the previously adopted value. {sup 84}Mo is an even-even N=Z nucleus lying on the proton dripline, created during explosive hydrogen burning in type I x-ray bursts in the rapid proton capture (rp) process. The effect of the measured half-life on rp-process reaction flow is explored. Implications on theoretical treatments of nuclear deformation in {sup 84}Mo are also discussed.
