Exploring nuclear optical potentials under similarity renormalization group transformations

Recent work has suggested that incorporating nonlocality in (d,p) scattering introduces sensitivity to high n-p momenta and the deuteron D-state probability [1,2]. This leads to the question of how similarity renormalization group transformations, which soften potentials and increase nonlocality, impact optical potentials. We explore this question using simple models. \\ \relax [1] G.~W.~Bailey, N.~K.~Timofeyuk and J.~A.~Tostevin, %``Sensitivity of ( d , p ) Reactions to High n-p Momenta and the Consequences for Nuclear Spectroscopy Studies,'' Phys.\ Rev.\ Lett.\ {\bf 117}, 162502 (2016) %doi:10.1103/PhysRevLett.117.162502 [arXiv:1609.07303]. \\ \relax [2] G.~W.~Bailey, N.~K.~Timofeyuk and J.~A.~Tostevin, %``Nonlocal nucleon-nucleus interactions in (d,p) reactions: Role of the deuteron D-state,'' Phys.\ Rev.\ C {\bf 95}, 024603 (2017) %doi:10.1103/PhysRevC.95.024603 [arXiv:1701.05853].
