FENDL/A-2.0 (March 1997).
Comprehensive neutron cross section library for 13006
neutron activation reactions with 739 target nuclides from H to Cm in the
incident energy range up to 20 MeV. The data are in ENDF format with some
modifications. Compared to the previous version FENDL/A-1.1, many nuclides and
reactions were added or revised. The evaluations were selected from major
activation libraries including EAF-4.1, ADL-3, JENDL/A-3.2 and others.
Available
on magnetic tape or by FTP file transfer. Summary documentation: IAEA-NDS-173.
FENDL/A-2.0 Processed Files
(FENDL2/A-MCNP, FENDL2/A-VITJ_E, FENDL2/A-VITJ_FLAT). Pointwise cross sections
(any resonance parameters contained in the original data files were converted to
cross sections) for 13006 activation reactions for 739 target nuclides
(including
metastable states), processed for use with the Monte Carlo neutron/photon
transport code MCNP, and as VITAMIN-J 175 multigroup data weighted with the
VITAMIN-E neutron weighting spectrum and with a constant (flat) weighting
spectrum. Available on magnetic tape or by FTP file transfer. Summary
documentation: IAEA-NDS-174 (March 1997).
FENDL/C-2.0 (March 1997).

data for the fusion reactions H-2(d,n)He-3, H-2(d,p)H-3, He-3(d,p)He-4,
H-3(t,2n)He-4, and H-3(d,n)He-4, in ENDF-6 format. The data for the first four
reactions are extracted from ENDF/B-6 (unchanged from previous version

an improved
evaluation by G.M. Hale and M. Drosg. Available on magnetic tape or by FTP file

format as well as processed into MCNP and REAC-compatible formats, are available
on magnetic tape or by FTP file transfer. Summary documentation: IAEA-NDS-178
(March 1997).
FENDL/E-2.0 (March 1997).
Selected evaluated neutron, photon interaction and
photon production cross sections in ENDF format, for 61 nuclides of importance
for coupled neutron-photon transport calculations for fusion applications, in
the
energy range 10-5eV to 20 MeV. Relative to the previous version FENDL/E-1, 19
evaluations were replaced and evaluations for six additional nuclides were
added.
The neutron interaction cross sections were selected from ENDF/B-6, JENDL-3,
JENDL-FF (Fusion File), BROND-2, and EFF-3 libraries, while the photon
interaction cross sections were taken from the ENDF/B-6 photon interaction
library. Available on magnetic tape or by FTP file transfer. Summary
documentation: IAEA-NDS-175.

Personal item
Dr. Hans-Dietrich Lemmel, the head of the Nuclear Data Center Unit and editor of
this Newsletter since it was started in 1979, retired in November 1996 after 32
years of service with the IAEA Nuclear Data Section. The staff of the unit
thanks him for his guidance throughout the years and will try hard to continue
the work in his spirit.
New data libraries
ENDF/B-6 Release 4 was received (distribution date February 1997).
It contains
(in the neutron sublibrary) new evaluations for five materials: Gd-152, Gd-154,
Ir-191 (new material), Ir-193 (new material), Pu-236, and minor updates for ten
other materials. See IAEA-NDS-100 Rev. 7 for details. This release also
contains updated comments in the high energy sublibrary. The updated files are
included in our online service NDIS and can also be obtained on magnetic tape.

Conference announcement
The next International Nuclear Physics Conference (INPC98) will be held
in Paris,
France, 24-28 August 1998, sponsored by IUPAP (the International Union of Pure
and Applied Physics) and organized by the two French agencies CEA and CNRS. It
will be in the spirit of the tri-annual IUPAP nuclear physics conferences (the
last ones were held in Beijing 1995 and Wiesbaden 1992) but will have a special
character in celebrating the centennial of the discovery of radioactivity by
Henri Becquerel and of the first radioactive elements by Pierre and Marie
Curie.
The topics will include: Quark and Hadron Dynamics; Quark Gluon Plasma; Nuclear
Reaction Dynamics and Nuclear Matter at High Temperature; Nuclear Structure:
many-body problem, nuclei at large deformation or at extrem isospin...; Nuclear
Astrophysics; Fundamental Interactions and Symmetries; Experimental Techniques
and Facilities: new opportunities; Impact of Nuclear Science on Society:
industry, medicine, environment, waste management, production of energy, art...
