Applications of Electromagnetically Separated Radioactive Isotopes at the Nobel Institute of Physics

Abstract

The radioactive isotopes prepared with the E. M. isotope separator at the Nobel Institute of Physics [1] have been used in a large variety of investigations. Table 1 gives an idea of the problems which are of current interest and those isotopes which have been separated. They fall mainly into five groups:

• A. Measurements of short half-lives by use of delayed coincidences,

• B. Search for very weak transitions, such as double quantum emission,

• C. Mass determination of products obtained in heavy-ion reactions,

• D. Nuclear spectroscopy of uranium fission products and

• E. Low energy β-spectroscopy.
