DREB2014 - Direct Reactions with Exotic Beams

The structure of nuclei at and beyond the proton-drip line is very interesting as they show very attractive features such as halo structures, mirror symmetry breaking and narrow resonances in the continuum. In addition, they are important in the understanding of the rapid proton capture nucleosynthethic process (rp process). Knowledge of the nuclear properties in the light proton drip line region are key inputs to network calculations of the rp-path. However, little spectroscopic information is known about the structure of 25P which is proton unbound. Up to now only an upper limit of the lifetime of the unbound ground state has been measured [1]. Here we present the asymptotic normalization coefficients (ANCs) for mirror states in 25P obtained from the neutron transfer reaction 24Ne(d,p)25Ne at 10.6 AMeV [2] and using proton resonance energies obtained from a two-body potential approach. Preliminary results from the analysis shows that the neutron stripping to the states of 25Ne is rather peripheral enabling the prediction of proton widths in 25P using the mirror symmetry.
