  As shown in Ref. \cite{Rod09}, the Fermi part $M_{F}^{0\nu}$ of the total
$0\nu\beta\beta$-decay nuclear matrix element $M^{0\nu}$ can be related to the
single Fermi transition matrix element between the isobaric analog state (IAS)
of the ground state of the initial nucleus and the ground state of the final
nucleus. The latter matrix element could be measured in charge-exchange
reactions. Here we discuss a possibility of such a measurement for $^{48}$Ca
and estimate the cross-section of the reaction $^{48}$Ti(n,p)$^{48}$Sc(IAS).
