The ^13 N+p elastic resonance scattering has been studied at the secondary radioactive beam facility of CIAE in inverse kinematics via a thick-target method. The excitation function for the ^13N(p,p) scattering was obtained in the energy interval of Ecru ≈0.5-3.2 MeV with a ^13 N secondary beam of (47.8±1.5) MeV. Careful analysis of the secondary beam components and extensive Monte-Carlo simulations enable the resolution of the experimental proton spectra. The resonance parameters for five low-lying levels in ^14 O were deduced by Rmatrix fitting calculations with MULTI7 and SAMMY-M6-BETA. The present results show general agreement with those from a recent similar work, and thus confirm the observation of a new 0^- level at 5.7 MeV in 140 with an improved width of 400(45) keV.
The elastic resonance scattering of ^12C+p has been studied in inverse kinematics via a novel thicktarget method at GIRAFFE facility of HI-13 tandem accelerator laboratory, Beijing. The recoil protons weremeasured by a AE-E counter telescope based on a large area double-sided silicon strip detector at laboratoryangles around θ0 = 15^o. The excitation function for ^12C(p,p) elastic scattering has been obtained over a wideenergy range of Ec.m. =0.31-3.45 MeV, which was explained quite well by the R-matrix calculation with known resonance parameters of the first three levels in ^13N nucleus. Thus it is demonstrated that the present setup can be directly applied to the study of elastic resonance scattering with secondary radioactive beams.
