| Popis: | Most of the sinks able to absorb the point defects created under irradiation exhibit a stronger elastic interaction with the interstitial defect I than with the vacancy defect V. This bias of their elastic interaction (EB) is supposed to automatically determine the concomitant absorption bias (AB) leading to an elimination flux of I always larger than the flux of V. We show in this contribution that the link between the EB and the AB is not as rigid as thought previously. On a model system we can produce situations where this rule is in trouble: a sink which is primarily designed to attract more I than V can however absorb more V than I if it is located in the vicinity of another competing sink with prevalent elastic properties. As a consequence, the imbalance between the I and V fluxes absorbed by a given sink cannot be deduced univocally from its elastic interaction with the two defects because it is heavily influenced by the boundary conditions which are adopted to make the quantitative evaluation.
