Abstract
The string-inspired technique is used for a first calculation of the one-lo op axialvector vacuum polarisation in a general constant electromagnetic fi eld. A compact result is reached for the difference between this tensor and the corresponding vector vacuum polarisation. This result is confirmed by a Feynman diagram calculation. Its physical relevance is briefly discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
