In his letter about depleted uranium, Clive Semmens writes of protactinium-234m (Pa-234m), the decay product of thorium ... be quickly and easily measured by gamma spectrometry.

Gamma decay, where an atomic nucleus emits an energetic ... the energy and momentum of the final products need to match. For alpha and gamma decays, they always did. But for beta decays?

Nuclear two-photon or double-gamma nuclear decay is an electromagnetic process in which a nucleus in an excited state emits two gamma rays simultaneously. This new type of decay was first ...

This database offers a variety of tables for all natural elements and includes the following data: isotopic composition, thermal radiative cross section (total and partial), Westcott g-factors, energy ...

Neutron-capture prompt-gamma activation analysis (PGAA) is particularly valuable as a non-destructive nuclear method in the measurement of elements that do not form neutron capture products with ...

Gamma ray emission causes no change in the number of particles in the nucleus meaning both the atomic number and mass number remain the same. All types of radioactive decay can be detected by a ...
