Absolute differential and integral cross sections for charge transfer of state-selected keV oxygen ion with oxygen(2)
Absolute differential and integral charge transfer cross sections have been measured for 0.5, 0.85, 1.5, 2.8, and 5.0 keV O$\sp+$ with O$\sb2$ at scattering angles between 0.01$\sp\circ$ and 3.50$\sp\circ$ in the laboratory ...
AN ATOMIC OXYGEN TARGET FOR DIFFERENTIAL CROSS SECTION MEASUREMENTS
Atomic oxygen, an abundant upper atmospheric species, is an important target in collisions involving fast ions and neutrals precipitating into the Earth's thermosphere. To facilitate the laboratory study of these collisions ...
Measurement of (p,n) thresholds at tandem energies
The "counter ratio" technique of Bonner, et al., for measuring neutron thresholds has been extended to bombarding energies greater than 6 MeV. Neutron background problems had previously precluded neutron threshold ...
Optical manipulation of helium(2(3)S) atoms with a diode laser
A commercial Spectra Diode Laboratories, 1.083 $\mu$m diode laser has been used to efficiently spin polarize an atomic beam of He(2$\sp3$S) metastable atoms by optical pumping on the $\rm 2\sp3S\sb1\rightarrow2\sp3P\sb1$ ...
Magnetic measurements on chrome-cesium alum below 1° K
The static and ballistic magnetic susceptibilities of a pressed powder sample of chrome-cesium alum, which was compounded in this laboratory, have been studied as a function of entropy at temperatures obtained by adiabatic ...
