Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Radioactivity, also known as nuclear decay, radioactivity, radioactive
disintegration or nuclear disintegration, is the progression by which an unstable atomic
nucleus drops energy by radiation. A material comprising unbalanced nuclei is
considered radioactive. Three of the most common types of decay are alpha decay (α -
decay), beta decay (β-decay), and gamma decay (γ-decay). The present chapter
envelops the fundamental understanding of radioactivity. It progresses through the
introduction to radioactivity, alpha decay, magnetic spectrometer, determination of
energy of α (Alpha) particle, Gamow’s Theory of Alpha decay, beta decay,
measurement of energy of beta particle and Neutrino Theory of Beta decay: (Pauli’s
Neutrino Hypothesis, Fermi theory of Beta decay, Gamma Decay, Measurement of
Gamma γ-Ray Energies.
