Annual Report. Part A: Studies in K-Capture Positron Branching Ratios. Part B: Search for a Low-Lying O+ State in Gallium-68

K-capture to positron branching ratios were measured in the decay of Na/ sup 22/, Co/sup 58/, and Ga/sup 68/ -- all pure Gamow-Teller emitters, using coincidence scintillation spectrometer techniques. The measured values are 0.105 plus or minus 0.004 for Na/sup 22/, 5.08 plus or minus 0.17 for Co/sup 58/, and 1.28 plus or minus 0.12 and 0.10 plus or minus 0.02 for Ga/sup 58/. From these the Fierz interference terra is computed to be b =--0.004 plus or minus 0.012, -0.004 plus or minus 0.14, --0-03 plus or minus 0.02, and +0.03 plus or minus 0.01, respectively. These results indicate that the Fierz interference in Gamow-Teller interaction is very small. The decay of 270 day Ge/sup 68/ was investigated in equilibrium with Ga/sup 68/ to look for a possible low-lying 0+ level in Ga/sup 68/ using x-ray--x-ray and x-ray- gamma -ray coincidences. The result was negative. Besides the 9 kev K x ray, the 1.07 Mev gamma ray in the decay of Ga/sup 68/ and annihilation radiation, no other gamma rays were detected (<8% of 1.07 Mev gamma ray). The number of positrons per 1.07 Mev gamma - quantum was determined as 19.47 plus or minus 2.10. The ratio of …

Compilation and Correlation of Experimental, Hypersonic, Stagnation Point Convective Heating Rates (open access)

Compilation and Correlation of Experimental, Hypersonic, Stagnation Point Convective Heating Rates

Experimental shock-tube data for the aerodynamic heating at the stagnation point on spherical bodies at superorbital and suborbital flight velocities (U/sub/0) have been compiled from a number of sources and compared to theoretical predictions. It was found that the empirical correlation given by Detra, Kemp and Riddell is remarkably close to a least-squares fit of the data. It is therefore recommended that their correlation be used for continuum flow theoretical predictions of the laminar hypersonic convective stagnation-point heating rate to spherical bodies in the region U/sub/0 - 6000 to 58,000 ft/sec.

City Smoke Ordinances and Smoke Abatement

From Introduction: "In connection with the fuel investigations conducted by the Bureau of Mines much information has been accumulated as to the smoke abatement activities in various cities. The essential features of the information are presented in this report, which, it is believed, will be of public interest and benefit, especially to those communities that are just beginning organized effort to abate unnecessary smoke."

"On the Precipice in the Dark": Maryland in the Secession Crisis, 1860-1861 (open access)

"On the Precipice in the Dark": Maryland in the Secession Crisis, 1860-1861

This dissertation is a study of the State of Maryland in the secession crisis of 1860-1861. Previous historians have emphasized economic, political, societal, and geographical considerations as the reasons Maryland remained loyal to the Union. However, not adequately considered is the manner in which Maryland understood and reacted to the secession of the Lower South. Historians have tended to portray Maryland's inaction as inevitable and reasonable. This study offers another reason for Maryland's inaction by placing the state in time and space, following where the sources lead, and allowing for contingency. No one in Maryland could have known that their state would not secede in 1860-61. Seeing the crisis through their eyes is instructive. It becomes clear that Maryland was a state on the brink of secession, but its resentment, suspicion, and anger toward the Lower South isolated it from the larger secession movement. Marylanders regarded the Lower South's rush to separate as precipitous, dangerous, and coercive to the Old Line State. A focus on a single state like Maryland allows a deeper, richer understanding of the dynamics, forces, and characteristics of the secession movement and the federal government's response to it. It cuts through the larger debates about the …
