Abstract
The Maxwellian averaged neutron capture cross section of 139La has been measured at kT = 25 keV to be 44.1 ±2.9 mb by means of the activation technique. A study of the precipice of the σN(A) curve at magic neutron shell 82 using the new cross section was carried out. The average time integrated neutron flux τ0 was found to be τ0 = (0.304±0.013)mb-1 at kT = 30 keV and an s-process abundance of 139La of 0.33±0.03 [Si = 106] was calculated.
