Ambiguity of gamma-ray tracking of "two-interaction" events
Tracking of gamma-ray interactions in germanium detectors can allow
reconstruction of the photon paths, and is useful for many applications.
Scrutiny of the kinematics and geometry of gamma rays which are Compton
scattered only once prior to full absorption reveals that there are cases where
even perfect spatial and energy resolution cannot resolve the true interaction
sequence and consequently gamma-ray tracks cannot be reconstructed. The photon
energy range where this ambiguity exists is from 255 keV to around 700 keV.
This is a region of importance for nuclear structure research where two-point
interactions are probable.Comment: 8 pages, 2 figure
University vaccine campaign increases meningococcal ACWY vaccine coverage
In this study, we report MenACWY vaccine coverage in first
year students arriving at the University of Nottingham (UoN)
in September 2015. We also report the uptake of MenACWY
vaccine offered to unvaccinated students via a campus-based
mass vaccination campaign as part of a local initiative by the
University of Nottingham Health Service (UNHS), in liaison
with UoN, during the registration period. [Taken from introduction
