Description
The initial condition in relativistic heavy-ion collisions is sensitive to the nuclear structure of the colliding nuclei. Experimental observations in U+U and isobar collisions have revealed nuclear structure effects, such as deformation or neutron skin. For smaller colliding systems such as $^{20}$Ne+$^{20}$Ne collisions, where the number of nucleons is limited, cluster models are typically used to describe the nuclear structure. We study the $5\alpha$ and $\alpha$+$^{16}$O cluster structure inside $^{20}$Ne within the microscopic Brink cluster model. Our study presents a full analytical calculation of eccentricities $\varepsilon_{n}$ and $\varepsilon_{n}$-related observables in most central Ne+Ne collisions. We demonstrate that the normalized symmetric cumulant $\rm NSC(3,2)$ and the Pearson correlation coefficient $\rho (\varepsilon_{3}^{2},\delta d_{\perp}/d_{\perp} )$ can enable us to study which potential cluster configuration is more significant in $^{20}$Ne. Our findings offer a novel strategy for identifying cluster structures inside $^{20}$Ne through the future Ne+Ne collision experiment at the LHC.
