Satellite measurements of auroral ultraviolet and 3914-A radiation were made November 9–11, 1965, as part of a coordinated program of luminosity, particle precipitation, and ion and electron number density measurements. Auroral ultraviolet radiation in the 1230- to 1840-A region was observed on mo...
The nuclear spectroscopy data so acquired allowed determination of the concentrations of elemental hydrogen [H], iron [Fe], and potassium [K] on Ceres. According to Prettyman et al. (2017),“measurements of hydrogen and iron provide constraints on the abundance of aqueous alteration products, ...
Neutron groups resulting from the alpha-particle bombardment of separated isotopes of potassium have been observed. Ground-state $Q$ values of -3.42ifmmodepmelsetextpmfi{}0.06 Mev for ${mathrm{K}}^{41}(ensuremath{alpha}, n){mathrm{Sc}}^{44}$ and -7.16ifmmodepmelsetextpmfi{}0.06 Mev for...

Small-angle neutron-scattering patterns from micelles of potassium salts of five octadecacarboxylic acids, differing only in number of double bonds or configuration, are reported. Degrees of aggregation vary between about 100 for potassium linolenate (three double bonds) to about 190 for potassium ste...
This is a technique that measures the natural level ofγ radiationemitted from the strata around the hole. High levels of activity are generally due to the presence of potassium (the40K isotope is slightly radioactive), which occurs in mica, feldspar, and some of the clay minerals. Intervals...

This method, targeting nitrogen, allows: (1) the determination of total-body nitrogen and, therefore, total-body protein, which is the principal nitrogen-containing component of the body; and (2) in combination with total-body potassium measurements, the indirect determination ofskeletal musclemass...

From such mechanisms of CR-39, recoiled protons, which are not desired etch pits in this study, are also detectable in BNCT irradiations. Considering these, to reduce the detection efficiency of recoiled protons, chemical etching treatments with potassium–hydroxide–ethanol–water solution with ...
