Abstract

Parity violating effects in the transmission and radiative capture of longitudinally polarized thermal neutrons have been observed for 117Sn and 139La targets. Helicity dependent asymmetries a = 106 (σ+-− σ)/(σ+ + σ) were found in the total cross section of 117Sn (a = 6.2 ± 0.7) and 139La (a = 9.0 ± 1.4), and also in the (n, γ) cross section of 117Sn (a = 22.6 ± 1.9) and of 139La (a = 16.1 ± 2.0).
