The time-dependent anisotropy of the differential 133-482 keV γ-γ angular correlation in synthetic, 3 and 24 h pile irradiated ( BPHA ) 4 Hf indicates the occurrence of considerable thermal neutron capture after-effects and suggest the formation of at least three chemical species in the irradiated complex.

The thermal neutron capture cross sections of Na23 and Mn55 have been determined using the activation method. The values are 0.53 ± 0.03 and 12.7 ± 0.3 barns respectively with respect to σAul97 = 93 barns. These agree well with recent pile oscillator results. The half-life for Mn56 is found to be 2.576 ± 0.002 hr.
