- Abstract
- Levels of Ir-194 were studied using neutron capture and (d,p) reaction
spectroscopy. A pair spectrometer was used to measure the high-energy gamma-ray
spectrum from thermal-neutron capture in an enriched Ir-193 target over the
energy range 4640-6100 keV. From the same reaction, low-energy gamma-radiation
was studied using curved-crystal spectrometers, and conversion electrons
were observed with magnetic spectrometers. Prompt and delayed gamma gamma-coincidences
were measured using semiconductor and scintillation detectors. Averaged
resonance capture measurements were performed with 2 keV and 24 keV neutrons
for primary transitions leading to excitation energies from 0 to 580 keV.
Using 22 MeV deuterons, the Ir-193(d,p) high resolution spectra were
observed with a magnetic spectrograph. The deduced nuclear level scheme of
Ir-194 includes 38 levels connected by 184 transitions. Unambiguous spins
and parities were determined for 25 levels. The rotor-plus-particle model
was used for the interpretation of the level scheme assuming a strong mixing
for Nilsson configurations having identical parities and K quantum numbers.
IBFFM model calculations were performed and the obtained results were
compared with the experimental level scheme. (C) 1998 Elsevier Science B.V.
