Phys. Rev. D 22, 313–321 (1980)New gravitational instantons and their interactionsReceived 7 November 1979; published in the issue dated 15 July 1980 We explore some of the possibilities for constructing new gravitational instantons. We find a new type, a rotating analog of the Taub-"bolt" situation, and we also rule out the possibility of various multi-instanton configurations. © 1980 The American Physical Society URL:
