Three neutron reactions leading to production of the rare gases Ar41 and Xe135 have been investigated. Single crystal samples of KF, CaF2, and BaF2 were irradiated in the Berlin reactor and the target-free absolute activities of the rare gas isotopes measured by a β-γ-coincidence method. The calculated cross sections areK41(n,p) Ar41: σ= ( 2,73±0,41) mb; σ0= (98,6±14,8) mb;Ca44 (n,a)Ar41: σ = (61,1 ±9,2) μb; σ0= (64,7± 9,7) mb;Ba138(n,a)Xe135: σ= ( 1,9 ±0,3) μb; σ0= ( 4,9± 0,7) mb.The first set of values are valid for a fission-neutron spectrum. The second set are calculated cross sections for the high energy plateau. They can be considered as valid for 15 MeV neutrons.
