You are cordially invited to attend the seminar entitled:

New theoretical uncertainties in predicting (d,p) cross sections

presented by

Natasha Timofeyuk
University of Surrey

(d,p) reactions are a popular tool of extracting spectroscopic information about nuclei. However, this information is affected by theoretical uncertainties of (d,p) cross sections predicted by widely-used codes based on certain direct reactions theories. In this talk I will describe a recent work at Surrey that aims to incorporate a realistic feature of nucleon optical potentials - nonlocality - into existing (d,p) theories accounting for deuteron breakup. This work has revealed a high sensitivity of (d,p) cross sections to deuteron wave function at very small separation between neutron and proton when nonlocal optical potentials are used thus creating new theoretical uncertainties. I will also talk about how including energy-dependence of nonlocal optical potentials adds to theoretical uncertainties and briefly mention an ongoing investigation clarifying the role of NNN forces in (d,p) reactions.
