Outlook

Transfer reactions are now proven as an effective experimental technique with radioactive beams. Reactions on p and d targets will allow experiments to probe single particle structure in new regions. Simply identifying the $\ell$ and E _</I>x of levels will give important information. Detailed tests of models will follow with the extraction of spectroscopic factors. Two-neutron transfer in inverse kinematics is challenging but, in addition to tritium targets, (9Be,7Be) and (10B,8B) are possible. Amongst topics awaiting study are: the evolution of pairing and shell gaps in weakly bound neutron rich isotopes, the cross-shell intruders near (Z,N)=(12,20) and (16,28), and the coexistence of collective and single particle structure in magic nickel isotopes. Transfer on deformed J $^{\pi}=0^+$ nuclei populates rotational bands with a `fingerprint' characteristic of the Nilsson orbital [3,18]. This could be used to identify the low(high)-$\Omega$ deformed orbitals underpinning coexisting prolate(oblate) shapes near N=Z=40. In many of these studies, the coincident detection of $\gamma$-rays will be crucial. It is a pleasure to acknowledge the insights gained through discussions with Nigel Orr, John Winfield and Simone Fortier.
