A series of neutron capture cross section measurements of interest to nuclear astrophysics
have been recently performed at n TOF, the neutron spallation source operating
at CERN. The low repetition frequency of the proton beam driver, the extremely high
instantaneous neutron flux, and the low background conditions in the experimental area
are optimal for capture cross section measurements on low-mass or radioactive samples.

A series of neutron capture cross section measurements of interest to nuclear astrophysics
have been recently performed at n TOF, the neutron spallation source operating
at CERN. The low repetition frequency of the proton beam driver, the extremely high
instantaneous neutron flux, and the low background conditions in the experimental area
are optimal for capture cross section measurements on low-mass or radioactive samples.
An overview of the measurements performed during the two experimental campaigns in
2002 and 2003 is presented with special emphasis on the measurement of the capture cross
sections of the Os isotopes relevant for the cosmochronology based on the Re/Os clock.
