In this invited response we answer all comments by Engelen and Hansen[arXiv:2207.07844]. We point out that the superfluid and superconductiveproperties of H(0) have been published previously. We explain some differencesbetween covalently bonded molecules and the molecules in the ultradense matterH(0) form, and explain some aspects of the energetics of H(0) molecules duringCoulomb explosions. We point out that the experimental spectra shown in ourpublication are not ion time-of-flight spectra but neutral time-of-flightspectra with the peak width given by the internal energetics and not byexperimental factors. We point out that no phase diagram has been measured forH(0). Further we point out that a Rydberg state is a hydrogenic state and thusthat all hydrogen atom states are Rydberg states. That Rydberg states alwayshave large principal quantum numbers is a complete misunderstanding. We pointout that a QM description of H(0) is published. We point out that theinternuclear distances in p(0), D(0) and pD(0) have been measured by rotationalspectroscopy in two publications for three different spin states. They aremeasured in the pm range with fm precision.
