We consider, in quantum scattering theory, symmetrised time delay defined in terms of sojourn times in arbitrary spatial regions symmetric with respect to the origin. For potentials decaying more rapidly than |x|− 4at infinity, we show the existence of symmetrised time delay, and prove that it satisfies an anisotropic version of Lavine’s formula. The importance of an anisotropic dilations-type operator is revealed in our study.
