Description
My activities in the NEPTUN project were in part focused on elaborating the SPADES code, capable of producing phase space factors and spectra for all two-neutrino double beta decay channels and the light neutrino exchange model of their neutrinonless conterparts. The codebase is mature, able to compute PSFs and spectra to the highest precision attainable numerically, includes the most relevant corrections and effects (e.g. screening, radiative, exchange effects). Other activities included helping in the quantification of uncertainties for studies related to electron capture.
I have also spent some time performing a couple of studies with Aagrah Agnihotri and Jouni Suhonen. These studies were related to the reactor antineutrino anomalies and involved computing antineutrino spectra and their associated uncertainties accounting for the uncertainty in the q-value, half life and branching ratio of the 94-98Y nuclei. The result here is a set of code that can compute such spectra by modifying only configuration files, which are well documented and intuitive to use. These codes combine several tools created by the jyväskylä group. My direct contributions were related to the statistical treatment of uncertainties.
Finally, with the help of A. Neacsu, I have learned how to use KSHELL and NuSHELLX and am now able to extract quantities relevant for the computation of double beta decay (nuclear excitation energies and one body transition densities).
