The Feynman diagram generator FeynArts and the computer algebra program FormCalc allow for an automatic computation of 2→2 and 2→3 scattering processes in High Energy Physics. We have extended this package by four new kinematical routines and adapted one existing routine in order to accomodate also two- and three-body decays of massive particles. This makes it possible to compute automatically two- and three-body particle decay widths and decay energy distributions as well as resonant particle production within the Standard Model and the Minimal Supersymmetric Standard Model at the tree- and loop-level. The use of the program is illustrated with three standard examples: [Formula: see text], [Formula: see text], and [Formula: see text].

A search was carried out for the α-particle decay of the 15∙1 MeV state in 12 C. The state was made by the 10 B ( 3 He, p ) 12 C reaction. The protons feeding the 15∙1 MeV state were seen in proton singles spectra and in coincidence with 15∙1 MeV γ -rays, but none were seen in coincidence with α -particles. Comparison with a nearby state known to decay virtually solely by α-particles established that the 15∙1 MeV state α -decays less than 20 % of the time. Combining this result with the results of γ-ray resonance scattering we find that ┌ α < 15 eV. The sensitivity of the experiment was limited by a continuum from the break-up of the 10 B + 3 He system.

AbstractThis review focuses on the chemistry and application of radium isotopes to environmental monitoring, analytical, and medicinal uses. In recent years, radium has been used primarily as a tracer to study the migration of radioactive substances in environmental systems. Tracing the naturally occurring radium isotopes in mineral and water sources allows for the determination of source location, residence time, and concentrations. An understanding of the concentration of radionuclides in our food and water sources is essential to everyone’s health as alpha particle decay is highly damaging in vivo. Due to this high radiobiological effectiveness, there is increased interest in using alpha-emitting radionuclides to prepare new, therapeutic radiopharmaceutical drugs. Selected studies from the recent literature are provided as examples of these modern applications of radium isotopes.
