We introduce a new observable, Anode, that allows to isolate the node in the S-partial wave distribution of the deuteron in high Q2 electro-disintegration processes with tensor polarized target. The node is a signature of nuclear repulsive core and represents a crucial test of its strength, size as well as the role of the relativistic and non-nucleonic effects in a deeply bound state. Within plane wave impulse approximation the node immitates a ``hole" through which incoming probe passes through without interaction. It is demonstrated that high Q2 electro-disintegration processes due to their strong anisotropy of final state interaction effects, allow to gain an unprecedented access to the node, opening up a new venue in probing elusive dynamics of the nuclear repulsive core.
