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...
Detection of xenon radioisotopes (radioxenons) has proven to be an important method for detecting nuclear explosions and is particularly well suited for detecting undeclared underground testing. The radioxenon isotopes ¹³¹mXe (t₁/₂ = 11.934 d), ¹³³mXe (t₁/₂ = 2.19 d), ¹³³Xe (t₁/₂ = 5.243 d) and ¹³⁵Xe (t₁/₂ = 9.14 h)...
Injection of a 2.0 mg Cd
²⁺
/kg B.W. (I.P. as CdC1
₂
in
.05 M NaAc, pH = 6.9-7.2, .15 M or p = .15 with NaCl) resulted
in a decrease in ceruloplasmin (EC 1.12.3) p-phenylenediamine
oxidase activity within one hour of injection.
Maximal decrease (40%) occurred within six...
¹³⁰ Sn and ¹²⁸Sn were separated from mixed fission products.
The decay of these isotopes were studied with Ge(Li),
LEPS, and plastic scintillator detector systems in single
and two parameter coincidence modes. The decay scheme constructed
for ¹²⁸Sn decay has levels at 0.0 (5+), 45.7 (4+),
77.8 (3+), 152.9 (2+),...
Samarium-neodymium data for authigenic ferromanganese
sediments from the oceans indicate that the Atlantic, Pacific, and
Indian Oceans each have a distinct range in Nd isotopic composition,
all of which are far less than ¹⁴³Nd/¹⁴⁴Nd ratios of source rocks with
oceanic affinities. Direct measurements of the Nd isotopic composition
of seawater...
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....
Alnus rubra (Bong. ) seedlings were grown in sand culture and
irrigated with nutrient solution containing CdCl₂
ranging from 5 μg to 100 mg per liter. Treatment of A. rubra seedlings for 4 weeks
with 50 and 100 mg CdCl₂
per liter of nitrogen-free nutrient solution
decreased in situ nitrogenase...
