Abstract
A measurement of resonant elastic scattering of Si-26+p was performed with a thick target using a Si-26 radioactive ion beam at the CRIB (CNS Radioactive Ion Beam separator) of the Center for Nuclear Study (CNS), the University of Tokyo. The excitation function of P-27 was measured successfully with the inverse kinematics method through a covered the range of excitation energies from E-x similar to 2.3 to 3.8 MeV, providing information about the resonance structure of this nucleus. The properties of these resonances are important to better determine the production rates of Si-26(p,g)P-27 reaction, which is one of the astrophysically important nuclear reactions to understand the production of the Al-26. Some new resonant states have been investigated, and determined their resonance parameters, such as excitation energies, proton partial widths, and spin-parities by R-matrix calculation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
