The momentum spectra of charged pions following antiproton annihilation at rest in carbon and uranium have been measured. This information complements our previous measurement of the neutral pion spectra. The total charged pion multiplicity is 2.84±0.10 and 2.47±0.09 for carbon and uranium, ...
X-ray photoelectron spectroscopy (XPS) is a proven tool to obtain information about local charge with atomic specificity in electronic ground states5. The tight localisation of core orbitals makes the method site selective. The ionisation potential (IP) measures the difference between neutral state an...
Briefly discuss the principle of Positron Emission Tomography (PET) paying particular attention to the properties of the radionuclides that are used and the method of determining the line along which each annihilation event occurred. Give one example of a radionuclide commonly used as well as one ...
