Theory of Superfluidity and Critical Velocity in Helium II

Description: The theory of superfluidity of helium II doesn't cover one important phenomenon--the existence of a critical velocity for which the theory is not able to explain quantitatively. This paper looks to conduct experiments on the need for substantial alterations of the helium II theory.

The Isotopic Conposition of the Oxygen of Carbonates as a Function of Temperature

Description: With the ubiquity of oxygen in the earth's crust and the accuracy with which differences in the isotopic composition of naturally occurring oxygen have been measured, oxygen isotopes are often used as indicators in studying the mechanism of natural processes

The Isotopic Abundance Ratio of Carbon in Meteorites

Description: The isotopic composition of chemical elements is determined by the nuclear process by which they are formed. To a certain extent, this abundance ratio is affected by all of the primary nucleogenetic processes involved in the formation of the substance in question.

The Raman Spectra and Structure of Perrhenium Acid and Perrhenate Ion

Description: The Raman spectrum shows that sulphate, selenate and perchloride ions have a tetrahedral structure in solution. Tellurium, molybdenum and tungsten should be surrounded by six oxygen atoms and should therefore form a octahedral structure. The author investigates the Raman-spectra of several perrhenates and of perrhenium acid.
