论文摘要
中子分布半径$ r _ {\ rm n} $的精确和与模型无关的确定，因此，原子核的中子皮肤厚度$ r _ {\ rm皮肤} $在核物理学，物理学和天体物理学中至关重要，但仍然是地际实验室的巨大挑战。我们认为，附近的核心爆发超新星（CCSN）在我们的银河系中可能会使中微子通量具有前所未有的高光度，提供了绝佳的机会来确定$ r _ {\ rm n} $和$ r _ {\ rm _ {\ rm skin} $，通过coherent弹性中性nucile-nucile-nucus-nucus sce $ ns $ ns $ ns ce $ n我们评估了通过CE $ν$ ns确定铅（pb）的$ r _ {\ rm n} $与附近的CCSN Neutrinos在Res-Nova项目中的潜力，该项目旨在使用一系列基于考古PB的基于Archogolical PB的高温检测器来狩猎CCSN Neutrinos。我们发现，对于$ r _ {\ rm n} $（$ \ rm n} $（$ \ sim 0.006 $ fm）的最终精度为$ r _ {\ rm rm skin} $ fm可以通过res-nova实现CCSN爆炸的最佳情况下，可以通过res-nova实现。
A precise and model-independent determination of the neutron distribution radius $R_{\rm n}$ and thus the neutron skin thickness $R_{\rm skin}$ of atomic nuclei is of fundamental importance in nuclear physics, particle physics and astrophysics but remains a big challenge in terrestrial labs. We argue that the nearby core-collapse supernova (CCSN) in our Galaxy may render a neutrino flux with unprecedentedly high luminosity, offering perfect opportunity to determine the $R_{\rm n}$ and $R_{\rm skin}$ through the coherent elastic neutrino-nucleus scattering (CE$ν$NS). We evaluate the potential of determining the $R_{\rm n}$ of lead (Pb) via CE$ν$NS with the nearby CCSN neutrinos in the RES-NOVA project which is designed to hunt CCSN neutrinos using an array of archaeological Pb based cryogenic detectors. We find that an ultimate precision of $\sim 0.1 \%$ for the $R_{\rm n}$ ($\sim 0.006$ fm for the $R_{\rm skin}$) of Pb can be achieved via RES-NOVA in the most optimistic case that the CCSN explosion were to occur at a distance of $\sim 1$ kpc from the Earth.
