Update on the structure of n-rich 52-56Ti

Neutron-rich nuclei above $^{48}$Ca are presently the subject of much theoretical and experimental focus because of the presence of a N=32 sub-shell gap [1]. The spectroscopy of these hard-to-reach nuclei has been carried out with a number of reactions including deep inelastic processes and fusion- evaporation utilizing extremely weak channels. An example of the latter is the use of the $^{9}$Be($^{48}$Ca,2p) reaction with a $\sim$1 $\mu$b cross section to investigate $^{55}$Ti. In this case, advantage is taken of the resolving power of the combination of the Argonne Fragment Mass Analyzer and the Gammasphere array. Recent experimental progress in the structure of the odd and even Ti isotopes will be presented and compared with shell model calculations carried out with recently developed effective interactions. \newline [1] R.V.F Janssens et al., Phys.
