Abstract
Located at the Spallation Neutron Source in Oak Ridge National Lab, the Nab experiment aims to yield a measurement of the electron-neutrino correlation parameter, a, and the Fierz interference term, b, in neutron beta decay. These parameters are located in the energy and the angular distribution of the particles produced through neutron beta decay. Using silicon detectors, a direct measurement of the phase space distribution of the resultant electron energy and proton momentum can be obtained. The silicon detectors of the Nab experiment will be tested using well-known radioactive isotopes. Simulations of systematic testing use the associated energy levels, decay probabilities, and decay options of radioactive sources such as Ce-139, Ba-133, and Sn-113 to determine the expected results of experimental testing. Presented here is an analysis of the Monte Carlo simulations of the radioactive decay of Ce-139, Ba-133, and Sn-113, and their ability to be useful to the Nab experiment as a whole.

Radioactive decay simulations for testing of the timing detectors in the Nab experiment
Located at the Spallation Neutron Source in Oak Ridge National Lab, the Nab experiment aims to yield a measurement of the electron-neutrino correlation parameter, a, and the Fierz interference term, b, in neutron beta decay.

The silicon detectors of the Nab experiment will be tested using well-known radioactive isotopes.
