Transmission, capture and self-indication measurements on197Au have been performed at the neutron time-of-flightfacility GELINA, operated by the European Commission, at EU-JRC-IRMM inBelgium. Part of this work was performed within the framework of the EFNUDATproject, with the objective to improve resonance parameters for the197Au(n, ¥ã) cross section. Resonance parameters, i.e.,energy, spin, parity, neutron and radiation width, have been deduced in theenergy domain up to 200 eV. A comparison with results of measurementsperformed at RPI and at n_TOF shows a good agreement betweenthe data sets. In particular the nuclear resonance parameters, of the firsts-wave resonance at 4.9 eV, extracted at RPI are in very good agreement withthe results of the present work.

Abstract
Transmission, capture and self-indication measurements on197Au have been performed at the neutron time-of-flightfacility GELINA, operated by the European Commission, at EU-JRC-IRMM inBelgium. Part of this work was performed within the framework of the EFNUDATproject, with the objective to improve resonance parameters for the197Au(n, ¥ã) cross section. Resonance parameters, i.e.,energy, spin, parity, neutron and radiation width, have been deduced in theenergy domain up to 200 eV. A comparison with results of measurementsperformed at RPI and at n_TOF shows a good agreement betweenthe data sets. In particular the nuclear resonance parameters, of the firsts-wave resonance at 4.9 eV, extracted at RPI are in very good agreement withthe results of the present work.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
