Abstract

The ³⁶Cl production mechanism in the atmosphere is of interest in understanding the formation of this cosmogenic radioisotope and its applications in geological studies. The ^36Ar(n, p)³⁶Cl reaction has been suggested by Onufriev as a source of ³⁶Cl in the atmosphere. Onufriev derived this estmation by assuming the ³⁶Ar(n, p)³⁶Cl reaction to be caused by slow neutrons with a cross section of the same order of magnitude as that of the ¹⁴N(n, p)¹⁴C reaction [1]. However, no data existed for the slow neutron cross section of ³⁶Ar(n, p)³⁶Cl. We irradiated enriched ³⁶Ar gas in a reactor and used the AMS technique to detect ³⁶Cl. We obtained an upper limit for the thermal neutron cross section of 1.5 mb. This value is three orders of magnitude lower than the value assumed by Onufriev.
