Alpha radioactivity in Indian cement samples
ABSTRACT Background: The essential constituents of cements like lime, silica and alumina are derived from earth’s crust in which radioactive elements like uranium, thorium etc are also present in varying amounts almost everywhere. These two elements are considered as the parent elements of uranium and thorium radioactive decay series in which radon and thoron are produced respectively as decay...
متن کاملAlpha-Particle Condensation in Nuclear Systems
The onset of quartetting, i.e. α-particle condensation, in symmetric nuclear matter is studied with the help of an in-medium modified four nucleon equation. It is found that at very low density quartetting wins over pairing, because of the strong binding of the α-particles. The critical temperature can reach values up to around 6 MeV. Also the disappearance of α-particles with increasing densit...
متن کاملDetection of High-Angle Alpha Particle Scattering through Gold Foil
In the beginning of the 20th century, physicists had begun to determine the structure of atoms. J.J. Thomson had discovered the presence of electrons negatively charged particles with a mass much less than the overall mass of the electron using cathode rays[1]. Thomson further hypothesized that the full structure of the atom consisted of electrons surrounded by a ”soup” of positive charge. This...
متن کاملOne Pot Synthesis of Alpha-Aminonitrile and Alpha-Amino Acid From Schiff Bases
Addition of Potassium cyanide to a mixture of Schiff base and lithium perchlorate afforded a-aminonitriles in high yields. Addition of potassium cyanide to a methanolic solution of Schiff base and phosphoric acid afforded a-aminonitriles. When the reaction mixture was refluxed it gave a-amino acids in high yields.
