    I - ISOTOPES and NUCLIDES

    Isotopes and Nuclides          /           Georges Audi    June 2000

    I would like  to  draw  the attention of our colleagues on the often
    encountered misuse of the word `isotope' instead of `nuclide'.

    Isotopes,  isotones,  isobars refer to series of nuclides having one
    same  number,  resp. Z, N, A. Therefore one can speak about isotopes
    of sodium, or isotones at N=82, or isobars at mass 144.
    Nuclide  designate one specific combination of neutrons and protons,
    e.g. 87Rb.

    The  SUNAMCO  commission  of  the  IUPAP  has pointed to this misuse
    already in 1987 in a document named:
    "Symbols, Units, Nomenclature and Fundamental Constants in Physics".
    In page 15 one can read:
        2.5.1 Nuclides
        A  species  of  atoms identical as regards atomic number (proton
        number)  and mass number (nucleon number) should be indicated by
        the  word  'nuclide',  not  by  the  word  'isotope'.  Different
        nuclides  having  the  same  mass  number  are  called 'isobaric
        nuclides' or 'isobars'.
        Different  nuclides  having  the  same  atomic number are called
        'isotopic nuclides' or 'isotopes'. etc...



    II - NEWS FROM EXPERIMENTS ON MASSES

    The Braunschweig-Mainz Collaboration /  Karl-Ludwig Kratz  June 2000

    Already   several  years  ago,  a  Braunschweig-Mainz  collaboration
    determined  Qbeta  values  of medium-mass fission products, first at
    the  TRIGA-reactor  at  Mayence and then in close collaboration with
    the group of Juha Äystö at the IGISOL mass separator at Jyväskylä.

    The  results  of  these  measurements are given in the AMDC as a TeX
    file  "experimental/qbeta.tex"  with  two  tables:  table 1 with the
    results obtained at Mainz and table 2 with the data taken at IGISOL.



    III - ENAM-2001: 3rd CONFERENCE on EXOTIC NUCLEI and ATOMIC MASSES
                                   /      Peter Dendooven    August 2000

    The 3rd International Conference on Exotic Nuclei and Atomic Masses,
    ENAM2001,  will  be  held  in  Aulanko near the city of Hämeenlinna,
    Finland  on  2-7  July 2001. The Aulanko natural park is in southern
    Finland, 100 km north of Helsinki. The site follows the tradition of
    the  ENAM  conferences  and  is surrounded by some of Finland's most
    beautiful nature, lakes and forests.

    The conference venue, Hotel Aulanko, is renowned for its 60 years of
    tradition  as  a  magnificent  location  for conferences and special
    occasions.  The  programme  will  consist of invited review talks on
    major  developments  in the area of exotic nuclei and atomic masses,
    plus   selected   oral   and   poster   contributions  on  important
    experimental and theoretical topics. Fields to be covered include:
        * Atomic masses and fundamental constants
        * Fundamental symmetries and interactions
        * Moments and radii
        * Forms of radioactivity
        * Direct reactions and nuclear spectroscopy
        * Nuclei at the drip lines
        * Cluster phenomena
        * Nuclear structure and shapes
        * Fission
        * Heaviest elements
        * Nuclear astrophysics
        * Experimental developments
        * Traps for radioactive isotopes
        * Applications of exotic nuclei

    The  ENAM2001  Conference is organized by the Department of Physics,
    University  of  Jyväskylä.  More  information  can  be  found on the
    ENAM2001 web site at http://enam2001.jyu.fi/.
