dc.descriptionThe results of background measurements with the second version of the BOREXINO Counting Test Facility (CTF-II), installed in the Gran Sasso Underground Laboratory, were used to obtain limits on the instability of nucleons, bounded in nuclei, for decays into invisible channels ($inv$): disappearance, decays to neutrinos, etc. The approach consisted of a search for decays of unstable nuclides resulting from $N$ and $NN$ decays of parents $^{12}$C, $^{13}$C and $^{16}$O nuclei in the liquid scintillator and the water shield of the CTF. Due to the extremely low background and the large mass (4.2 ton) of the CTF detector, the most stringent (or competitive) up-to-date experimental bounds have been established: $τ(n \to inv) > 1.8 \cdot 10^{25}$ y, $τ(p \to inv) > 1.1 \cdot 10^{26}$ y, $τ(nn \to inv) > 4.9 \cdot 10^{25}$ y and $τ(pp \to inv) > 5.0 \cdot 10^{25}$ y, all at 90% C.L.
