(Texas A&M University. Libraries, 1971)Differential cross sections for the elastic scattering and inelastic scattering to the low-lying states in ¹⁴⁴Sm and ¹³⁸Ba have been measured using 50 MeV α particles and 30 MeV protons on ¹⁴⁴Sm and 50 MeV α particles on ...
-
(Texas A&M University. Libraries, 1992)The electrical breakdown and field emission are important factors which limit the maximum electric field of rf cavities and performance of high gradient accelerators. In order to improve our understanding of rf breakdown, ...
-
(Texas A&M University. Libraries, 1979)Electron-hydrogen atom scattering is one of the most fundamental electron-atom scattering problems, providing excellent grounds for testing various theoretical approximation methods. Since the target atom wave functions ...
-
(Texas A&M University. Libraries, 1970)It is often assumed that the strength limiting process in the fracture of semicrystalline polymers is the rupture of tie molecules connecting the crystalline regions along the fiber axis. The strain and rupture behavior ...
-
(Texas A&M University. Libraries, 1976)Electron-impact ionization cross sections for atomic oxygen are calculated in the Born approximation. The initial bound state of atomic oxygen is represented by a configuration interaction wavefunction. Configurations used ...
-
(Texas A&M University. Libraries, 1972)The concept of a multi-photomultiplier tube radiation detection system that electronically displays the image of the spatial distribution of radiation interactions within a thin scintillator has been developed. Small ...

(Texas A&M University. Libraries, 1965)The ultrasonic attenuation has been measured in liquid argon by pulse techniques with a single quartz transducer, variable path length apparatus. Measurements have been made at temperatures between 84°K and 112°K with ...
-
(Texas A&M University. Libraries, 1994)Excitation energy deposition and light particle emission for fissioning nuclei with excitation energies from 2 to 6 MeV/nucleon are studied for the reaction of 20 AMeV 20Ne with [144,148,154]Sm and 10, 17, 25 and 35 AMeV ...
-
(Texas A&M University. Libraries, 1991)Weak localization effects have been studied experimentally and theoretically in semiconductor superlattices. Low temperature parallel magnetotransport measurements of GaAs/AlGaAs multilayer periodic structures have revealed ...
-
(Texas A&M University. Libraries, 1970)A kinematically complete experiment for the reaction d(p,2p)n has been performed for an incident proton energy of 28.61 MeV. Simultaneous detection of the two protons was made by two systems of 96 scintillation detectors ...
-
(Texas A&M University. Libraries, 1972)An investigation of the temperature dependence of the thermomagnetic torque has been carried out in normal hydrogen and normal deuterium. Measurements were made with a very sensitive torsion pendulum over a range of ...
-
(Texas A&M University. Libraries, 1969)An investigation of the thermomagnetic torque, or Scott effect, has been carried out in several concentrations of ortho and para-hydrogen. Measurements were made with a sensitive torsion pendulum over a range of temperatures ...
-
(Texas A&M University. Libraries, 1971)The Hall mobility of the proton in single crystal ice doped with HF was found to be + 4.2 X 10⁻³ cm²/V-sec at -5°C by means of an ac technique. The best run has an error of ± 1.0 X 10⁻³ cm²/V-sec; but, all of the data ...

High mass diffractive dissociation at 27.5 GeV proton-proton interactions in exclusive final states (Texas A&M University. Libraries, 1990)A study of diffractive production in 27.5GeV/c proton-proton interactions is presented. The detector that was used to take the data and the techniques that were used to analyze the data are also discussed. The results are ...
-
(Texas A&M University. Libraries, 1974)Spectra of inelastically scattered alpha particles from [superscript 40]Ca and [superscript 208]Pb have been obtained using a charge-division position sensitive proportional counter. Strongly excited bound states were ...
-
(Texas A&M University. Libraries, 1985)An investigation of scintillations in ground-level cosmic ray muons has been conducted using a muon telescope constructed at Texas A&M University. The power density spectrum of the muon counting rate was calculated and the ...
