    Notes: Abstract We report the first measurement of the total charge-loss cross section σtot=σem+σnuc and partial cross sections (for ΔZ=1, 2, ..., 9) of 11.4 A GeV197Au nuclei in various targets. The large Coulomb barrier for Au reduces the electromagnetic contribution σem in a Pb target to only 18% of σnuc, compared with ∼ 70% for 14.5 A GeV28Si and 120% for 200 A GeV32S. With σem taken to be ∝Z T 1.8 , σnuc can be fitted with σnuc=α(A P 1/3 +A T 1/3 −b)2, with b=0.83 and α=59 mb, essentially the same as found at energies of 1 to 2 A GeV. Electromagnetic partial cross sections for ΔZ=1 exceed ∼ 40 mb in the Pb, Sn, Cu, and Fe targets and are substantial for larger values ofΔZ in the heavier targets.

    Science requirements for Heavy Nuclei Collection (HNC) experiment on NASA Long Duration Exposure Facility (LDEF) Mission 2 (1991)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: The Heavy Nuclei Collection (HNC) is a passive array of stacks of a special glass, 14 sheets thick, that record tracks of ultraheavy cosmic rays for later readout by automated systems on Earth. The primary goal is to determine the relative abundances of both the odd- and even-Z cosmic rays with Z equal to or greater than 50 with statistics a factor at least 60 greater than obtained in HEAO-3 and to obtain charge resolution at least as good as 0.25 charge unit. The secondary goal is to search for hypothetical particles such as superheavy elements. The HNC detector array will have a cumulative collection power equivalent to flying 32 sq m of detectors in space for 4 years. The array will be flown as a free-flight spacecraft and/or attached to Space Station Freedom.

    Evidence for detection of a moving magnetic monopole (1975)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: A very heavy particle passed through a balloon-borne stack of Cherenkov film, emulsion, and Lexan sheets. In 33 Lexan sheets it produced tracks expected of either a nucleus with Z ranging between 125 and 137 and with beta less than about 0.92 or a magnetic monopole with g = 137e. Its track structure in emulsion indicated it was moving downward with beta equal to 0.5 (plus 0.1 or minus 0.05) and was either a nucleus with Z equal to 80 or a monopole with g = 137e. These facts strongly favor identification of the particle as a magnetic monopole of strength g = 137e and mass greater than 200 times proton mass.

    Mesoscale acid deposition modeling studies (1989)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: The work performed in support of the EPA/DOE MADS (Mesoscale Acid Deposition) Project included the development of meteorological data bases for the initialization of chemistry models, the testing and implementation of new planetary boundary layer parameterization schemes in the MASS model, the simulation of transport and precipitation for MADS case studies employing the MASS model, and the use of the TASS model in the simulation of cloud statistics and the complex transport of conservative tracers within simulated cumuloform clouds. The work performed in support of the NASA/FAA Wind Shear Program included the use of the TASS model in the simulation of the dynamical processes within convective cloud systems, the analyses of the sensitivity of microburst intensity and general characteristics as a function of the atmospheric environment within which they are formed, comparisons of TASS model microburst simulation results to observed data sets, and the generation of simulated wind shear data bases for use by the aviation meteorological community in the evaluation of flight hazards caused by microbursts.
