Spontaneous vacuum decay of supercritical nuclear composites

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

We show that in deep inelastic heavy ion collisions withZ 1+Z 2> 173 the spontaneous decay of the neutral vacuum by emission of positrons may be isolated from other competing positron producing processes. From the details of the spontaneous positron spectrum information about the nature (lifetime, shape and angular momentum) of the composite nuclear system may be derived.
