论文摘要
Qed-Vacuum Energy $ \ hbox {$ \ cal e $} _ {vp} $在库仑超临界条件下$ z> z_ {cr，1} $在本质上是非扰动方法探索的。结果表明，在超临界区域$ \ hbox {$ \ cal e $} _ {vp} $是库仑源参数的降低函数，导致衰减到负范围为$ \ sim -sim -s -z^4/r $。还讨论了在核转化对背景上可以明确检测到真空正电子的发射的条件。 In particular, for a super-critical dummy nucleus with charge $Z$ and $R(Z) \simeq 1.2 \ (2.5\, Z)^{1/3}$ fm the lowest $1s$-level dives into the lower continuum at $Z_{cr,1} \simeq 170$ (the model of uniformly charged ball) or $Z_{cr,1} \simeq 173 $（球形外壳模型），因此出现了带有诱导电荷的真空外壳（-2美元| e | $），Qed-Vacuum被充电，但是在这两种情况下，可靠的自发性正值检测的实际阈值不少于$ z^\ ast ast ast ast \ simeq 210 $。
The properties of the QED-vacuum energy $\hbox{$\cal E $}_{VP}$ under Coulomb super-criticality condition $Z>Z_{cr,1}$ are explored in essentially non-perturbative approach. It is shown that in the supercritical region $\hbox{$\cal E $}_{VP}$ is the decreasing function of the Coulomb source parameters, resulting in decay into the negative range as $\sim - Z^4/R$. The conditions, under which the emission of vacuum positrons can be unambiguously detected on the nuclear conversion pairs background, are also discussed. In particular, for a super-critical dummy nucleus with charge $Z$ and $R(Z) \simeq 1.2 \ (2.5\, Z)^{1/3}$ fm the lowest $1s$-level dives into the lower continuum at $Z_{cr,1} \simeq 170$ (the model of uniformly charged ball) or $Z_{cr,1} \simeq 173$ (the spherical shell model), whereupon there appears the vacuum shell with the induced charge (-$2|e|$) and the QED-vacuum becomes charged, but in both cases the actual threshold for reliable spontaneous positrons detection is not less than $Z^\ast \simeq 210$.
