Study of proton resonances in Ne-18 via resonant elastic scattering of F-17+p and its astrophysical implication

The proton resonant properties in Ne-18, which determine the reaction rate of the key stellar O-14(alpha,p)F-17 reaction, have been studied by using a technique of proton resonant elastic scattering of F-17+p. A 4.22 MeV/nucleon F-17 radioactive ion (RI) beam was produced via a projectile-fragmentation reaction, and separated by a Radioactive Ion Beam Line in Lanzhou (RIBLL). By bombarding a thick (CH2)(n) target, the energy spectra of the recoiled protons were measured by two Delta E-E silicon telescopes at the center-of-mass scattering angles of theta(c.m.)approximate to 175 degrees +/- 5 degrees, theta(c.m.)approximate to 152 degrees +/- 8 degrees, respectively. Several proton resonances in Ne-18 were observed clearly. A further R-matrix analysis of the experimental data is under way to determine the resonant parameters. The present work reports the preliminary results briefly.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000302529300006&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, MultidisciplinarySCI(E)3ARTICLES32-S365
