In the backdrop of many models, the heavy cluster structure of the ground state of 24Mg has been probed experimentally for the first time using the heavy cluster knockout reaction 24Mg(12C,212C)12C in the quasifree scattering kinematic domain. In the (12C,212C) reaction, the direct 12C-knockout cross-section was found to be very small. Finite-range knockout theory predictions were much larger for (12C,212C) reaction, indicating a very small 12C−p>12C clustering in 24Mgb>(g.s.)b>. Our present results contradict most of the proposed heavy cluster (12C+12C) structure models for the ground state of 24Mg.
