For example, in 2005, Andreas Rathke of the European Space Agency, publishing in the "New Journal of Physics", wrote that Mills' description of quantum mechanics is "inconsistent and has several serious deficiencies", and that there is "no theoretical support of the hydrino hypothesis". Rathke said it would be helpful if Mills' experimental results could be independently replicated, and suggested that any evidence produced should be reconsidered in the context of a conventional physical explanation. One inconsistency of Mills' CQM with quantum mechanics regards its inability to be reconciled with the probability density function in quantum mechanics. Rathke stated, "However, while solutions of the Schrödinger equation with n<1 indeed exist, they are not square integrable. This violates not only an axiom of quantum mechanics, but in practical terms prohibits that these solutions can in any way describe the probability density of a particle." In the same year, the "Journal of Applied Physics" published a critique by A.V. Phelps of the 2004 article, "Water bath calorimetric study of excess heat generation in resonant transfer plasmas" by J. Phillips, R. Mills and X. Chen. Phelps criticized both the calorimetric techniques and the underlying theory described in the Phillips/Mills/Chen article. The journal also published a response to Phelps' critique on the same day. In 2005 Šišović and others published a paper describing experimental data and analysis of Mills' claim that a resonant transfer model (RTM) explains the excessive Doppler broadening of the Hα line. Šišović concluded that: "The detected large excessive broadening in pure hydrogen and in Ne–H2 mixture is in agreement with CM Model and other experimental results" and that "these results can't be explained by RTM". The collision model explanation for excessive broadening of the Hα line is based on established physics.
