Abstract
The retention of 82BrO3− in KBrO3 activated with fast nuetrons is about 18% at ambient temperature. Annealing at 523 K gives an increase to 50%. Simultaneously produced 81mSe appears in about 90% as SeO42− at room temperature, which percentage increases to near 100% after annealing. The 76As recoil atoms appear 100% as AsO43−. A description is proposed, based on processes with different spectra of energies of activation. A model is given for these processes, based on the hypothesis that the recoil atom stabilizes in the host lattice in a form which is compatible with, and may be imposed by the crystal structure of the host lattice.
