Project Physics Text 6, The Nucleus.
Harvard Univ., Cambridge, MA. Harvard Project Physics.
Nuclear physics fundamentals are presented in this sixth unit of the Project Physics text for use by senior high students. Included are discussions of radioactivity, taking into account Bacquerel's discovery, radioactive elements, properties of radiations, radioactive transformations, decay series, and half-lives. Isotopes are analyzed in connection with positive rays, mass spectrographs, notations for nuclides and nuclear reactions, relative abundances, and atomic masses. Nuclear structures and reactions are studied by using proton-electron and proton-neutron hypotheses with a background of discoveries of neutrons, neutrinos as well as artificial transmutation and artificially induced radioactivity. Information about binding energy, mass-energy balance, nuclear fission and fusion, stellar nuclear reactions, nuclear force and model, and biological and medical application of radioisotopes is given to conclude the whole text. Historical developments are stressed in the overall explanation. Problems with their answers are provided in two categories: study guide and end of section questions. Besides illustrations for explanation use, charts of elementary particles and physical constants with conversion factors are also included in this text unit as appendices. The work of Harvard Project Physics has been financially supported by: the Carnegie Corporation of New York, the Ford Foundation, the National Science Foundation, the Alfred P. Sloan Foundation, the United States Office of Education, and Harvard University. (CC)
