REF.: G15114 Title: Standard model masses and models of nuclei... Author(s): Rivero A. Dear Dr. Rivero , The manuscript you submitted to Europhysics Letters has been sent to the Editor in Chief who asked the opinion of an expert in the field. I regret to inform you that on the basis of the attached referee report, Professor Jerome cannot accept your manuscript for publication and therefore supports the decision of Professor Auerbach. Yours sincerely, on behalf of Professor D. Jerome Mrs. Y. Sobieski Staff Editor REPORT The subject could have been quite interesting. However the speculation of the author appears to be beyond the possibility to describe nuclear spectra in a proper way with physical justification. Introducing boson masses out of the already known description of the IBM interacting boson model needs more sound theoretical justification. In conclusion the article in the present form is not recommended for publication.
