The proton resonant properties in 18Ne, which determine the reaction rate of the key stellar 14O(α,p)17F reaction, have been studied by using a technique of proton resonant elastic scattering of 17F+p. A 4.22 MeV/nucleon 17F 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 ΔE-E silicon telescopes at the center-of-mass scattering angles of θc.m.≈175°±5°, θc.m.≈152°±8°, respectively. Several proton resonances in 18Ne were ob served 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.

All reaction cross sections, elastic scattering angular distributions, double differential cross sections, and the γ production data of n+Pu reaction in the energy region up to 20 MeV were calculated. Pretty good theoretical results in accordance with experimental data were obtained and they are comparable with those given by ENDFB-6 and JENDL-3 libraries.

According to A. B. Migdal’s prediction that a pion condensate should exist in ordinaryfinite nuclei, a nucleon density modulation due to pion condensate has been obtained frompseudovector pion nucleon coupling and phenomenological effective repulsion *** on the nucleon density modulation, we study the effects of pion condensate in somenuclear phenomena, such as high energy particle nucleus scattering, X-ray energy spectrumof muonic atom and nuclear binding *** results strongly indicate that there aresome sufficient opportunities in these processes for pion condensate to manifest itself andthe condensate could help us to improve the agreement between theory and experiments formany processes.
