Abstract: (Elsevier)
Parity violating effects in the transmission and radiative capture of longitudinally polarized thermal neutrons have been observed for 117 Sn and 139 La targets. Helicity dependent asymmetries a = 10 6 ( σ + -− σ − )/( σ + + σ − ) were found in the total cross section of 117 Sn ( a = 6.2 ± 0.7) and 139 La (a = 9.0 ± 1.4) , and also in the (n, γ) cross section of 117 Sn ( a = 22.6 ± 1.9) and of 139 La ( a = 16.1 ± 2.0).
