    AME-FUTURE

    Last April, the "NIPNET workshop on Precision Atomic Masses",
    held in Saariselkä (Finland), offered the opportunity of informal
    discussions about the future of the Atomic Mass Evaluation.

    Senior scientists, from most of the major places in the world
    where precise mass measurements are performed or will be
    performed in the very near future, exchanged ideas about the
    future of the Atomic Mass Evaluation, possible participation
    of their institute in the coming Ame2008, and the new
    organization after 2008.

    Further discussions and developments are planned during the
    ENAM-2004 conference, next September. Institutes and
    universities that feel they can contribute are encouraged to
    take contact (audi@csnsm.in2p3.fr) before the conference.


    76Se from SMILETRAP

    In the process of the mass evaluation, the evaluator must
    always be carefull to use only the primary information.
    While doing this, unfortunately, an accident occurred in the
    Ame2003 for the publication of 2001Do08.
    In this paper three results were given for 76Ge, 76Se and for
    their difference (of higher precision, due to drastically
    reduced systematic uncertainties in their combination).
    We should have used the 76Se and the 76Ge-76Se result and
    not the 76Ge in order not to use twice the same info.
    Unfortunately, in the process we accidentaly dropped also 76Se.

    Using this 76Se result will give, as expected, improved
    values in both 76Se and 76Ge mass-excesses:
        76 Ge = -73212.863 (0.091) keV
        76 Se = -75251.866 (0.075) keV
    Their mass difference 76Ge-76Se and uncertainty, which were
    the main physics output of the paper, remain unchanged.
    We apologize for any resulting inconveniency for the user,
    and to the Smiletrap team who has done a wonderful work.
