We investigate the possibility of a spontaneous collapse of the nuclei constituting the water molecule. We show that, due to a practically exact agreement of the energy of the p + p + 16O threshold and a resonance state of the 18Ne nucleus, the probability of nuclear fusion involvingp+p+ 16O → 18Ne*(4.522, 1-) in the rotationally excited H2O molecule is significantly enhanced. The calculation of the fusion probability is performed using a scheme analogous to the linear combination of atomic orbitals (LCAO), well known in the theory of molecules.
