Title = Nucleon Transfer and the Two-Faced Nature of 48K

Abstract
<blockquote>
Nucleon transfer reactions allow us to populate nuclear states with very specific structure in a very selective fashion. This makes the selected states relatively easy to identify and they are also the states that the shell model should be most successful in describing - so these experiments allow us to test (and hence improve) the shell model and its extrapolations. This remains true, even if the precise value of the "spectroscopic factors" - that we use in describing the structure -  are a matter of some debate. The introductory part of the talk will examine the meaning of "spectroscopic factor", some of the challenges in deducing experimental values and the reasons for choosing  a pragmatic way forward. Some new experimental results for 48K will be described, recently obtained in an experiment with a reaccelerated beam of radioactive 47K from SPIRAL1 and a silicon array operated with the AGATA gamma-ray array and the VAMOS magnetic spectrometer. These new results greatly extend the knowledge of excited states in 48K, but also show up some interesting challenges due to the coexistence of two different proton configurations at the same excitation energies. Implications for ever-more-neutron rich nuclei will be discussed and finally a few features of the new FAUST array for transfer studies will be described.
