In this project we measure the neutron capture cross section of ²⁰⁸Pb. We began by calibrating our silicon detector with ²⁰⁴Tl. Two experiments were then performed, the first in December of 1999 and the second in March of 2000. Both experiments were performed in the nuclear reactor of the Radiation...
When a nucleus is in an excited state, it will decay to lower energy by emitting photons. Often there are several intermediate stages in a decay cascade. Occasionally the photons in a cascade will be emitted in coincidence. This will be resolved by the detector not as two distinct photons,...
The neutron capture cross sections of ¹⁰⁶Cd, ¹⁰⁸Cd, ¹¹⁰Cd, ¹¹²Cd, ¹¹⁴Cd and ¹¹⁶Cd
were determined in the present project. Four different OSU TRIGA reactor facilities were
used to produce redundancy in the results and to measure the thermal cross section and
resonance integral separately. When the present values were compared...
The thermal cross sections and resonance integrals for neutron capture by ⁷⁴,⁷⁸,⁸⁰,⁸²Se were measured using the same procedure and equipment for all of the isotopes. Uncertainty and absence of accurate previous values for several isotopes introduces a need of measuring these parameters using similar techniques. This was done using OSU’s...
The static and dynamic electric quadrupole moments of even-even
and odd-A nuclei with 150<A<190 have been compiled and analyzed in a
systematic way, in order to extract the best set of intrinsic
quadrupole moments Q₀. The intrinsic quadrupole moments of the odd-A
nuclei have been used together with a compilation...
¹⁸⁶Ir gamma transitions are studied via the reaction
Hf (¹⁴N, xn) Au at ¹⁴N beam energy 130 MeV. The beta decay
chain of Au is Au + Pt + Ir + Os. Singles and coincidence
data are from measurements by Ge gamma-ray detectors.
Conversion electrons are measured by Si(Li) detector....
An experiment has been conducted using a triple directional
correlation method developed by K. S. Krane, R. M. Steffen and R.
M. Wheeler (ref. 3). This method is presented and two normal detection geometries are introduced. The performance of the N1- and N2-
geometry was studied in four experiments using...
Measurements have been made of γ -γ directional correlations on the
following cascades, following the decay of ¹¹¹Pd and ¹⁰⁹Pd :
In ¹¹¹Ag : (454, 633, 762 - 391) keV (526, 797 -633) keV
(526, 797 -[633] -391) keV
In ¹⁰⁹Ag : (390, 413, 424, 551, 558 - 311) keV...
