摘要：

The deposition profiles that form around precipitates undergoing energetic transmutation reactions can be used to study the effects of helium, hydrogen and lithium on microstructural development during neutron irradiation. A completely general derivation has been performed to determine the deposition profile concentrations for any transmutation reaction and precipitate/matrix combination. Calculations of the deposition profiles were performed for the **1**0B(n, alpha )**7Li reaction and selected precipitate/matrix stopping power ratios. With increasing ratio the deposition profiles become more uniform but the reaction products are deposited over larger volumes leading to lower concentrations in the matrix.
