Quasi-elastic (QEL) scattering measurements have been performed using a 28 Si projectile off a 90 Zr target at energies around the Coulomb barrier. A Bayesian analysis within the framework of coupled channels (CC) calculations is performed in a large parameter space of quadrupole and hexadecapole deformations (β 2 and β 4) of 28 Si. Our results unambiguously show that 28 Si is an oblate shaped nucleus with β 2=-0.38±0.01 which is in excellent agreement with results from electromagnetic probes. The sign and magnitude of quadrupole deformation along with a precise value of hexadecapole deformation (β 4=+ 0.03±0.01) of 28 Si have been determined for the first time using QEL scattering. A remarkable agreement is obtained between the experimental and calculated β 4 values of 28 Si based on Skyrme-Hartree-Fock method. The present results demonstrate the strong sensitivity of the quasi-elastic scattering to the sign and magnitude to the ground state deformation parameters, thus affirming its suitability to be used for rare exotic nuclei using low intensity RIBs.
