Study of 0 states at iThemba LABS
The very strong attractive forces between nucleons in a nucleus cause the protons and neutrons each to pair off into time reversed orbits with magnetic quantum numbers m and -m. Thus the angular momentum of each nucleon is opposite to its pairing partner, giving zero angular momentum for the pair. In nuclei with even numbers of both protons and neutrons (e–e) all the nucleons are paired off and...
متن کاملIn-situ gamma-ray mapping of environmental radioactivity at iThemba LABS and associated risk assessment
In-situ and ex-situ measurements of environmental radioactivity were made on the iThemba LABS (iTL) grounds in South Africa. The MEDUSA and HPGe detector systems were used to make insitu and ex-situ measurements, respectively. The MEDUSA was mounted ∼0.5m above the ground on a 4× 4 vehicle to traverse [at ∼2m · s−1] the accessible portions of the iTL grounds. Spatial data (via a GPS receiver) w...
متن کاملBeam experiments with the Grenoble test electron cyclotron resonance ion source at iThemba LABS.
At iThemba Laboratory for Accelerator Based Sciences (iThemba LABS) an electron cyclotron ion source was installed and commissioned. This source is a copy of the Grenoble Test Source (GTS) for the production of highly charged ions. The source is similar to the GTS-LHC at CERN and named GTS2. A collaboration between the Accelerators and Beam Physics Group of CERN and the Accelerator and Engineer...
متن کاملDouble Chooz at Nevis Labs
This report presents my work for Double Chooz at Columbia University’s Nevis Labs during the 2008 Summer REU program. Double Chooz is a neutrino experiment that will either measure or constrain the neutrino mass mixing parameter θ13. Columbia University and collaborators are responsible for the Double Chooz Outer Veto, which detects incoming Cosmic Muons to prevent false signal in the main dete...
متن کاملXENON REU at Nevis Labs, Columbia University
It is believed that baryons, which form ordinary, luminous matter, only represent about 4% of the composition of the universe; the rest is comprised of about 73% dark energy and 23% dark matter, both of which currently have unknown sources. Dark energy explains the acceleration of the expansion of the universe, while dark matter accounts for some ”missing mass,” whose presence can be inferred f...
