Pressure-Volume-Temperature Measurements on Solids (open access)

Pressure-Volume-Temperature Measurements on Solids

From abstract: "The results of recent measurements on the equations of state of sodium and xenon are discussed. The experimental data for each of these are analyzed to show that the isothermal compressibility is solely a function of volume within experimental accuracy. The basic differences between the low temperature PV relationships for sodium and xenon are shown to be easily understandable in terms of the elementary theories of these substances. The range of experimental pressures (to 20 kbars) and temperatures (20°K to the triple point) is sufficiently great so as to produce significant changes in the lattice thermal properties in each case. These changes are indicated through the use of zero pressure heat capacity data in combination with the equation of state data to calculate the volume and temperature dependence of the Debye Θ. The result is quite spectacular for xenon, where a pressure of 20 kbars roughly doubles ΘD."

Radiations of 6.7d U²³⁷ (open access)

Radiations of 6.7d U²³⁷

Abstract: The radiations of U²³⁷ have been studied using a magnetic lens beta ray spectrometer and scintillation spectrometers for betas and gammas singly and in coincidence. A beta with an end point energy of 245 keV was found along with evidence for the existence of lower energy components. Gammas of energy 27, 42, 49, 59, 166, 208, 269, 354, 431, and 467 keV were found, and probably a gamma of 102 keV. The decay scheme constructed gives a total decay energy for this isotope of 512 keV.

Stabilizer for Temperature Control Equipment (open access)

Stabilizer for Temperature Control Equipment

From abstract: "A simple electronic circuit is described, the use of which greatly improves the temperature regulations obtainable with Beta equipment. The circuit utilizes the time derivative of the temperature to counteract oscillation and overshoot. No other changes are required in existing equipment for installation of the stabilizer."
