Query: A forgotten publication of Ettore Majorana on the improvement of the
  Thomas-Fermi statistical model   Ettore Majorana proposed an important improvement to the Thomas-Fermi
statistical model for atoms, with a communication at the general meeting of the
Italian Physical Society, held in Rome, on December 29th, 1928, regularly
published on Nuovo Cimento. This communication did not receive any mention,
neither in the numerous publications of Fermi and his associates on the
subject, nor in the further reconstructions of the life and activity of Ettore
Majorana. The Majorana proposal was not accepted by Enrico Fermi for years, and
forgotten. However, it was finally exploited, without reference, in the 1934
conclusive paper by Fermi and Amaldi on the statistical model for atoms. We
analyze the improved model proposed by Majorana, with the help of unpublished
notes, kept in the Majorana Archives in Pisa. Moreover, we trace the path
leading Fermi to the eventual late acceptance of Majorana improvement, also
with the help of the material in Fermi Archives in Pisa. The conclusion is that
Ettore Majorana played an effective leadership in Rome for the very conceptual
formulation of the statistical model for atoms.
