摘要: We show that in deep inelastic heavy ion collisions withZ1+Z2> 173 the spontaneous decay of neutral vacuum by emission positrons may be isolated from other competing positron producing processes. From details spectrum information about nature (lifetime, shape and angular momentum) composite nuclear system derived.
