A.; Karachuk, J.; Gelovani, L. K.; Gridnev, T. G.; Sosnin, A. N.; Dec. 31, 1998; 15p; In English Report No.(s): DE99-607967; JINR-E-1-98-51; No Copyright; Avail: Department of Energy Information Bridge Energetic secondary fragments produced in the interaction of (41-44) GeV (sup 12)C ions with copper exhibit experimentally a broader angular distribution as compared to energetic secondary fragments produced in the interactions at a lower (sup 12)C-energy (15-25) GeV when studied with radiochemical techniques. Such a different experimental behaviour of secondary fragments produced by (sup 12)C ions of the same two energy groups is not observed, when these secondary fragments are investigated with a propane bubble chamber. Separation of secondary particles is described.

Details are given on the status of the Database and preparation of the TECDOC, two major results of the project. Actions and deadlines are specified towards finalizing these results in the near future.

The project aims to produce an IAEA Photonuclear Data library and a TECDOC ’’Handbook on Photonuclear Data’’. Summarized is the status of the project along with future tasks towards its completion in 1999. An Appendix includes nine extended abstract of presented papers. A separate indexing was provided for each abstract.

isotopes. The method and program were successfully used to adjust the data of natural Fe and Fe-54,56,57,58 of CENDL-2.1, as well as to adjust the data of natural Ni and its isotopes Ni-58,60,61,62,64.

At the same time the cross sections of 40 reactions which we have measured since 1989 have been compiled and evaluated. A brief description of experimental measurement of activation cross sections is given. The data measured after 1995 by ourselves are listed in Table 4 and our evaluations for 40 reactions are listed in Table 5, respectively. A graphical intercomparison with available experimental data is given in appendix.

P.; Devkin, B. V.; Fursov, B. I.; Kobozev, M. G.; Talalaev, V. A.; Oct. 31, 1998; 34p; In English Report No.(s): DE99-607941; INDC(CCP)-417; No Copyright; Avail: Department of Energy Information Bridge Measurements of neutron leakage spectra from two shells of pure vanadium having wall thicknesses of 3.5 cm and 10.5 cm with a 14 MeV neutron source at the center are reported. The neutron leakage spectra were measured by the time-of-flight method from 15 MeV down to 50 keV. Descriptions of the experimental arrangement, the time-of-flight spectrometer, the measurements and data reduction procedures are given. Corrections connected with neutron multiple scattering in the neutron source, deviations from spherical symmetry and others were estimated by the Monte-Carlo technique. Also, the response function of the spectrometer was determined and folded with the calculated spectra to allow meaningful calculation-experiment comparisons even near the 14 MeV peak. Three-dimensional Monte-Carlo calculations were made with the MCNP code, using the EFF-3, FENDL-1 and JENDL-FF nuclear data libraries. The total leakage fluence is correctly predicted or slightly overestimated by all these evaluated data. However, its breakdown into energy bins shows considerable over estimations near 0.1 MeV for FENDL-1 and JENDL-FF and near 10 MeV for JENDL-FF, while EFF-3 on the whole reproduces the leakage spectra best. An analysis of existing differential experimental V(n,xn) data at 14 MeV incident energy agrees with these findings.

Performed under the CRP on measurement, calculation and evaluation of photon production data Final Report Simakov, S. P.; Pavlik, A.; Vonach, H.; Hlavac, S.; Sep. 30, 1998; 60p; In English Contract(s)/Grant(s): IAEA-7809/RB Report No.(s): DE99-607938; INDC(CCP)-413; No Copyright; Avail: Department of Energy Information Bridge The aim of the paper is to collect and examine the status of the experimental data on discrete (gamma)-ray production cross sections via (n, x(gamma)) reaction for practically important nuclei at 14 MeV incident neutron energy. From this point of view, the available experimental cross sections for all reliable (gamma)-ray transitions, measured by high energy resolution in- beam technique, were compiled in the report. This experimental base was critically checked from the point of view of influence of different experimental factors and evaluated experimental cross sections and uncertainties were received. The present status of experimental data against practical demands was established. The FENDL-1, ENDF/B6 and BROND-2 libraries were checked as well to search whether the discrete photon production cross sections were presented there and how they agree with available experimental data.
