Studying dynamical polarization in the breakup of $^{17}$F*

Fluorine-17 is a drip-line nucleus where the proton is bound by 0.6 MeV. It is predicted that the valence proton would be pushed away from the target nucleus and shielded by the $^{16}$O core when $^{17}$F is incident on a high Z target. This resembles the tail of a comet pointing away from the sun when it flies close to the sun. The phenomenon is caused by a dynamic polarization effect which is of order Z$^{3}$. The relative importance of the effect is therefore expected to be smaller on a target of lower Z. We have measured inclusive and exclusive breakup of $^{17}$F bombarding $^{58}$Ni and $^{208}$Pb targets at an energy of 10 MeV per nucleon. The breakup yield of $^{17}$F will be compared between the two targets and compared to model calculations to study this dynamic polarization effect.
