Jeff Blackmon: Nuclear Physics on Accreting Neutron Stars


Jeff Blackmon stressed the importance of experimental measurements of (p,g) and (a,p) reactions to accreting neutron stars. Current experiments are using indirect techniques to locate important resonances for these reactions. Specifically mentioned two direct measurements, the first was performed at Oak Ridge studying f17(p,g). Important resonance was measured, but direct capture rate still needs to be constrained. Secondly, he mentioned o14(a,p) measured at CRIB (RIKEN) which is 50-80% different from the recommended REACLIB rate.

To measure many of these reactions more low energy rare isotope beams are needed. Combined with new high resolution detectors such as ANASEN these important X-ray burst ignition rates can be better constrained.
