I show that particle collider experiments on relativistic nuclear collisions can serve as direct probes of the deformation of the colliding nuclear species. I argue that collision events presenting very large multiplicities of particles and very small values of the average transverse momentum of the emitted hadrons probe collision geometries in which the nuclear ellipsoids fully overlap along their longer side. By looking at these events one selects interaction regions whose elliptic anisotropy is determined by the deformed nuclear shape, which becomes accessible experimentally through the measurement of the elliptic flow of outgoing hadrons.

Investigating $^{238}$U Deformation via Dilepton Production in Relativistic Heavy-Ion Collisions
In a transport-model study of U+U collisions at 193 GeV, dilepton yields normalized by charged multiplicity are shown to scale linearly with the square of the nuclear quadrupole deformation beta_2, with stronger sensi...

Heavy quark polarization anisotropy as a novel probe of fireball geometry
Heavy-flavor polarization harmonics are introduced as observables whose Fourier coefficients are claimed to be proportional to the initial fireball spatial eccentricities.

Nuclear Physics Confronts Relativistic Collisions Of Isobars
RHIC isobar data are explained by different shapes of 96Ru and 96Zr, with 96Zr showing a large octupole deformation, so nuclear structure uncertainty, not the magnetic field, dominates the observed ratios.
