Abstract
Resonances in perturbed angular correlations due to crossing hyperfine levels have, so far, been observed on two cascade transitions, the 172 – 203 keV cascade1) in 127I and the 55 – 188 keV cascade2) in 125I. According to the theory3) the shape of the resonance signal in the usual geometry (magnetic field perpendicular to the detector plane) depends strongly on the angle Φ between the two γ rays. In particular at angles Φ = 5π/4, 3π/4 a pure dispersive shape is expected.
