Nuclear short-range correlations (SRCs) induce high-momentum/high-energy fluctuations in the nuclear medium. In order to assess their impact on nuclear bulk properties, like nuclear radii and kinetic energies, it is instrumental to determine how SRCs are distributed in phase space as this sheds light on the connection between their appearance in coordinate and momentum space. Using the lowest-order correlation operator approximation (LCA) to include SRC, we compute two-dimensional nuclear Wigner quasiprobability distributions $w(r,k)$ to locate those $(r,k)$ phase-space regions that are most heavily impacted by SRCs. The SRC-induced high-momentum components find their origin in a radial range that is confined to the nuclear interior. Significant SRCs strength is generated in the full momentum range $0\le k\lesssim 5{\text{fm}}^{-1}$ covered in this work, but below the Fermi momentum those are dwarfed by the mean-field contributions. As an application of $w(r,k)$, we focus on the radial dependence of the kinetic energy T and the momentum dependence of the radius $r_{\text{rms}}$ for the symmetric nuclei ${}^{12}\text{C}$, ${}^{40}\text{Ca}$ and the asymmetric nucleus ${}^{48}\text{Ca}$. The kinetic energy almost doubles after including SRCs, with the largest increase occurring in the nuclear interior $r\lesssim 2$ fm. The momentum dependence of the $r_{\text{rms}}$ teaches that the largest contributions stem from $k\lesssim 2$ fm⁻¹, where the SRCs induce a slight reduction of the order of a few percent. The SRCs systematically reduce the ${}^{48}\text{Ca}$ neutron skin by an amount that can be 10%.

核短程相关性 (SRC) 会引起核介质中的高动量/高能波动。为了评估它们对核体积特性（如核半径和动能）的影响，确定 SRC 如何在相空间中分布是有帮助的，因为这揭示了它们在坐标空间和动量空间中的外观之间的联系。使用最低阶相关算子近似 (LCA) 来包含 SRC，我们计算二维核 Wigner 准概率分布$瓦(r,克)$ 找到那些 $(r,克)$受 SRC 影响最严重的相空间区域。SRC 诱导的高动量分量起源于仅限于核内部的径向范围。在整个动量范围内产生显着的 SRC 强度$0\le 克\lesssim 5{\text{调频}}^{-1}$在这项工作中涵盖，但在费米动量之下，平均场贡献相形见绌。作为应用$瓦(r,克)$，我们关注动能T的径向相关性和半径的动量相关性$r_{\text{均方根}}$ 对于对称核 ${}^{12}\text{C}$, ${}^{40}\text{钙}$ 和不对称核 ${}^{48}\text{钙}$. 包括 SRC 后动能几乎翻了一番，其中最大的增加发生在核内部$r\lesssim 2$调频。的动量依赖$r_{\text{均方根}}$ 教导说最大的贡献来自 $克\lesssim 2$fm ^-1，其中 SRC 引起几个百分点的轻微减少。SRC 系统地减少了${}^{48}\text{钙}$ 中子皮肤的量可以是 10%。
