摘要：

We observed the bound-state beta(-) decay of fully ionized Re-87 nuclei circulating in a storage ring. With two independent methods the time dependent growth of hydrogenlike Os-187 ions has been measured and a half-life of 32.9+/-2.0 yr for bare Re-187 nuclei could be determined, to be compared with 42 Gyr for neutral Re-187 atoms. With the resulting log ft value of 7.87+/-0.03 the half-life of Re-187 ions in any ionization state can be calculated. Thus one can correct the Re-187-Os-187 galactic chronometer calibration, by taking account of the beta(-) decay enhancement in stellar interiors, which will leas to a more accurate estimate of the galactic age.
