Currently, the structure of the 3bf28db0ef18" title="Click to view the MathML source">X(3872)$X(3872)$ meson is unknown. Different competing models of the $c\overline{c}$ exotic state 3bf28db0ef18" title="Click to view the MathML source">X(3872)$X(3872)$ exist, including the possibilities that this state is either a mesonic molecule with dominating 3b0f02">$D^0{\overline{D}}^{鈦?/mo><mn>0</mn>}+c.c.$ composition, a 3bcadb0cd7e67f23bf3c3cc9">$c\overline{c}q\overline{q}$ tetraquark, or a $c\overline{c}$-gluon hybrid state. It is expected that the 3bf28db0ef18" title="Click to view the MathML source">X(3872)$X(3872)$ state is rather strongly coupled to the 3b6407e46bb3fa4a833ebb459f8">$\overline{p}p$ channel and, therefore, can be produced in 3b6407e46bb3fa4a833ebb459f8">$\overline{p}p$ and $\overline{p}A$ collisions at PANDA. We propose to test the hypothetical molecular structure of 3bf28db0ef18" title="Click to view the MathML source">X(3872)$X(3872)$ by studying the D   or ${\overline{D}}^{鈦?/mo>}$ stripping reactions on a nuclear residue.
