    Optogalvanic signals from argon metastables in a rf glow discharge (1989)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: Laser optogalvanic (LOG) signals at 667.7, 751.5, and 696.5 nm from the 3 P1 and 3 P2 levels of Ar were studied at a pressure of 250 mTorr in a rf glow discharge. Signals with unexpected signs and time dependences were found. The results are interpreted as being due to radiative trapping effects and collisional mixing between resonance and metastable levels. An average electron energy of 2.1 eV is derived from modeling the data.

    Heavy-ion excitation of rare-gas excimers (1987)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 62 (1987), S. 357-361

    Notes: Beams of high-energy heavy ions (Ar and U) from the UNILAC accelerator have been used to excite rare gases at pressures near 1 bar. The dominant spectroscopic feature observed in Ar, Kr, and Xe gases was molecular excimer emission at the second excimer continuum at 130, 150, and 170 nm, respectively. The excimer radiation was studied as a function of time (with respect to the excitation pulse), ion-beam current, pressure, and excitation density. The efficiency of excimer production from heavy-ion-beam energy was found to be several percent. Details of spectral shape, especially the ratio of first-to-second continuum emission, were found to depend on pressure and exciting beam type.

    Isotope selective laser enhancement of the Li+H2 reaction (1987)
    Springer
    Applied physics 43 (1987), S. 247-251

    Notes: Abstract The enhancement of the Li+H2→LiH+H reaction due to laser excitation of the Li atom to the2p state has been investigated using absorption techniques. Using a rate equation model we obtain from our data a reaction cross-section σ[Li(2p)+H2→LiH+H]=(0.10±0.03)Å2 at 515°C. By selectively exciting one Li isotope the reaction is made isotope selective, suggesting an efficient means of isotope separation.

    Laser production of polarized beams and targets (1985)

    Notes: Abstract Hyperfine interaction techniques have historically been applied to produce polarized nuclei. The use of optical pumping with tunable lasers is a new hyperfine interaction method which dramatically extends the range of nuclear species which can be polarized, as well as the fluxes and densities which can be achieved and the temperature range in which experiments can be carried out. Lasers are ideally suided for the production of polarized atomic beams, as will be illustrated for the cases of6,7Li,23Na and3He. Techniques for polarizing dense atomic vapors will be described with an emphasis on achieving full Doppler coverage by the method of velocity changing collisions. Experiments leading to the production of a6Li target for a parity non-conservation study of the nuclear reaction6Li(α,γ)10B will be reviewed and results obtained to date presented.

    Notes: Abstract The use of lasers for nuclear physics research is widespread and growing rapidly. The major impact in nuclear structure research has come from nuclear size and shape determinations for nuclei far from stability via high resolution isotope shift measurements. In addition, systematic data on nuclear magnetic and quadrupole moments have been obtained via the hyperfine splitting resolved in laser fluorescence studies of atomic spectra in both stable and unstable systems. The tunability, high intensity and inherent polarization of laser light can be used to polarize atomic nuclei for nuclear reaction studies. The rapid efficient polarization of unstable nuclei with lasers also presents opportunities for new research in nuclear physics. In this paper the physics of the laser interaction for the studies indicated will be introduced. Some examples of work completed and in progress will be presented primarily from on-line laser studies at charged particle accelerators. Extensions of current research, particularly with respect to possible studies of short-lived nuclei, are discussed and the synergistic effects of certain advances in quantum electronics and nuclear physics described.

    Bound-state beta-decay and kinematic search for neutrino mass (1987)

    Notes: Abstract A new method involving Doppler spectroscopy with laser techniques is proposed to observe bound-state β-decay of tritium. This process, although theoretically expected to occur, has not yet been observed. The proposed method is, in principle, capable of exposing a finite mass of the neutrino. The low source temperatures and laser spectroscopic resolution necessary for a neutrino mass measurement, although extremely difficult to achieve, appear accessible with conceivable advances of these techniques.
