Description
The ratio of the neutron capture cross sections for 186Os and 187Os was measured at the 25-keV iron-filtered neutron beam facility of a 10-MW reactor. A value of 0.41 +- 0.04 was obtained. On the bases of this ratio, the age of the universe was determined via the Re--Os β-decay clock to be approximately 19 x 109 years
