Pairing Correlations effect on static and dynamical properties of nuclei
D. Lacroix1
(28/11/2011)

In this talk, I will make a short review on recent progress we have made on the treatment of pairing in finite many body systems like nuclei. While pairing correlations are known to significantly affect nuclear properties, some aspects of pairing are still difficult to describe. For instance pairing correlation close to magicity requires to properly describing finite size effects like particle number conservation. The possibility to start with an approach breaking and restoring particle number in the Energy Density Functional theory (also called Skyrme or Gogny Hartree-­‐Fock) has led to important debate [1-­‐8]. New approaches, that are density functional friendly, have been recently proposed to incorporate pairing in nuclei. Examples of applications of these approaches to the spectroscopy of nuclei will be presented [9-­‐12]. Pairing is also expected to affect reaction mechanism, like transfer, breakup or fusion. While pairing is currently most often incorporated in the description of static properties of nuclei, these correlations have been rarely included in microscopic transport theories. Recently, we have proposed two approaches to treat pairing in dynamics. Illustrations on the break-­‐up of nuclei and on the evaporation of particles will be shown [13].
