Query: Electro-weak production of pseudovector C-even heavy quarkonia in
  electron-positron collisions on Belle II and BES III   It is shown that the molecular model for the X{3872) state contradicts the
new experimental data as well as the old ones. It is suggested to study the
\chi_{c1} and \chi_{b1} states in the e+e-\to\chi_{c1}/\chi_{b1} reactions.
