Investigation of stellar Si-26(p,gamma)P-27 reaction via Coulomb dissociation

The Coulomb dissociation of the proton-rich nuclei P-27 was studied experimentally using P-27 beams at 57 MeV/nucleon with a lead target. The radiative widths of the low-lying excited state in (27)p were deduced. The resonant capture reaction rate of stellar Si-26(p,gamma)(27)p through these states was estimated using the measured radiative widths. The astrophysical implications obtained from the extracted reaction rate will be discussed.
