In this reply to an additional Comment by Hansen and Engelen it is shown that there is no violation of the baryon number conservation ‘law’ in the nuclear reactions in H0). In numerous well-known studies from large groups, baryons are both created and annihilated, without breaking the baryon number conservation ‘law’. This point was misunderstood in the Comment. H(0) molecules have very little in common with covalently bonded H2 molecules. The smallest H(0) molecules are H3(0) and H4(0). The picometer bond distances in H(0) are measured by the kinetic energy release in Coulomb explosions by neutral fragment time-of-flight experiments (not in TOF-MS experiments as stated in the Comment). The bond distances are further measured with femtometer precision in rotational spectroscopy experiments, with spin resolution for s = 2, 3 and 4. Many different molecular forms are observed for p(0), D(0) and pD(0).
