The carbon is photoelectron spectrum of CO₂ has been measured with very high photon energy resolution. The natural lifetime of the carbon is hole state has been determined from a series of spectra taken at photon energies of 308, 320, and 330 eV. The measured values of the lifetimes show...
Four to six one-gram specimens separated by a distance of
several inches were obtained from each of 23 large chondritic
meteorites (approximately 1 kg each) representing the olivine bronzite
(H5), olivine hypersthene (L6) and enstatite (E5) classifications.
Each specimen was analyzed for Na and Mn via instrumental neutron
activation analysis...
High-precision instrumental neutron activation analysis has
been used to determine Al, Na, Mn, Sc, Cr, Fe, Co, and Ni in a
suite of more than 500 chondrules from 26 distinct meteorites. These
meteorite specimens represent the H, L, LL and C chemical classes
and most of the petrologic types. In...
Basalts of both Eocene and Miocene age from several groups
along the Oregon and Washington coasts have been analyzed for some
major, minor, and trace elements using instrumental neutron activation analysis (INAA). The rare earth element (REE) patterns observed
in these samples are used for comparisons within the groups studied...
An apparatus and procedure are described for investigating
selective adsorption from a binary vapor mixture as a function of
pressure. The technique measures both total mass adsorption and
adsorbed-phase composition.
Development of the method is outlined. Possible sources of
error are analyzed and are found to be either nonexistent or...
