This work was undertaken to obtain a reasonably complete list of the Ar lines that appear in hollow-cathode (HC) spectra. The older Ar linelists do not have the precision one wants in analyzing FTS spectra, and the available interferometric values -

We use time-resolved laser-induced fluorescence to measure the lifetime of 186 Fe levels with energies between 25 900 and 60 758 cm . Measured emission branching fractions for these levels yield transition probabilities for 1174 transitions in the ra

Transition probabilities for 2835 lines in Mo I between 2548 A and 10565 A have been measured by combining radiative level lifetimes, excited level populations measured in an inductively coupled plasma (ICP) source, and emission branching ratios meas

The Na23(p,α)Ne20 reaction has been studied for proton bombarding energies in the range 100 to 450 keV. Four narrow resonances were observed at proton bombarding energies Ep=286, 338, 374, and 445 keV. Excitation functions were taken at each of thes

Transition probabilities for twenty nine lines in Fe I ( 2656≦ λ ≦ 5379 A ) have been measured by combining beam-foil lifetime measurements for six levels in Fe I with measurements of the branching ratio for all known transitions which depopulat

The lifetimes of five levels in Fe II have been determined by the beam-foil method. Measurements were made at several energies between 200 and 400 keV using both 5 and 10 μg/cm2 carbon foils. The various results for a given level agree to within ±8

The Q value for the reaction B10(He3, N12)n has been measured by observing the (N12)5+ recoil ions in a magnetic spectrometer at 10-MeV bombarding energy. Observations at 1.7° and 7.0° laboratory angle yield Q=1.570±0.025 MeV, based on the ThC' al

The simplest method for measuring atomic transition probabilities is a two step process requiring (1) the radiative lifetime of the upper level of the transition and (2) the branching fraction, the probability that the upper level decays via the part

The momentum spectrum of the alpha particles from the Be/sup 9/(p, alpha )Li/sup 6/ reaction was measured in a magnetic spectrometer at 30 deg with 10- Mev incident proton energy. The discrete alpha-particle groups observed correspond to states in Li
