Abstract
X-ray bursts have been suggested as a possible site for the astrophysical -process. The time scale for the process is governed by -decay half-lives of several even-even waiting point nuclei, in particular, . A half-life for was determined by observing delayed 84-keV rays depopulating a isomer at 312 keV in the daughter . As this half-life is lower than many previously predicted values, the calculated excessive production of nuclides in astrophysical x-ray burst scenarios is reduced, and less extreme conditions are necessary for the production of heavier nuclides.
