Query: On the extra factor of two in the phase of neutrino oscillations   Attempts to modify the standard expression for the phase in neutrino
oscillations by an extra factor of two are based on misuse of quantum
mechanics. Claims to present Bruno Pontecorvo and his coauthors as
``godfathers'' of this ``extra 2'' factor are easily disproved by unbiased
reading their articles.
