If neutron absorption leads to radioactivity, column four lists its half-life. Usually, this activity is caused by radiative capture of neutrons; in those few 

The Atlas of Neutron Capture Cross Sections (NGATLAS) contains cross sections data of neutron induced reactions for targets up to, and including, curium (Z=96). It comprises 739 target isotopes with half-lives above 0.5 day. Cross sections to ground, first and second isomers are listed separately.

Introduction Although, the radiative neutron capture reactions on 14C and 14N at astrophysical energies do not take part in the main thermonuclear cycles [1–3] directly, they can
