Previous methods relied on cubic voxelization to create three-dimensional bodies from nuclear theory data points, leading to inaccurate estimations of geometric properties. This work introduces the alpha shapes method as a superior alternative for constructing three-dimensional solid bodies from point cloud data and calculating Minkowski Functionals. Through test cases comparing voxelization and alpha shapes, as well as analysis of pasta structures obtained through classical molecular dynamics, we demonstrate that the alpha shapes method provides more accurate geometric representations and simplifies the calculation of Minkowski Functionals. We use Diode, a Python library implementing alpha shape calculations, to verify previously observed correlations between pasta shapes and their position in the Curvature-Euler Characteristic plane. Our analysis, extending across various temperatures and densities, reveals a density-dependent trend in pasta shapes that is relatively temperature-independent. The method is also tested satisfactorily with neutron star matter. These findings provide a quantitative framework for characterizing the evolution of nuclear pasta structures and offer a new computational tool for researchers studying these phenomena through different theoretical approaches.</div></div>","PeriodicalId":19246,"journal":{"name":"Nuclear Physics A","volume":"1064 ","pages":"Article 123225"},"PeriodicalIF":2.5,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144895330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lett. <strong>146</strong>, (2024), 14001], a novel relativistic parameterisation of the energy density functional (EDF) at local density was integrated into the coherent density fluctuation model (CDFM). This approach employed the density-dependent DD-ME2 parameter within the relativistic Hartree-Bogoliubov framework, alongside the well-established non-linear NL3 force parameter, to investigate the surface properties of a few doubly-magic nuclei. In the present work, we extend this new relativistic EDF formulation to a much broader region: the evolution of shell structure across several open- and closed-shell nuclei of intermediate-mass isotopic chains, specifically Kr (<span><math><mi>Z</mi><mo>=</mo><mn>36</mn></math></span>), Sr (<span><math><mi>Z</mi><mo>=</mo><mn>38</mn></math></span>), Te (<span><math><mi>Z</mi><mo>=</mo><mn>52</mn></math></span>), Xe (<span><math><mi>Z</mi><mo>=</mo><mn>54</mn></math></span>), Ba (<span><math><mi>Z</mi><mo>=</mo><mn>56</mn></math></span>), Ce (<span><math><mi>Z</mi><mo>=</mo><mn>58</mn></math></span>), Nd (<span><math><mi>Z</mi><mo>=</mo><mn>60</mn></math></span>) and Sm (<span><math><mi>Z</mi><mo>=</mo><mn>62</mn></math></span>).
