Continuum discretised coupled-channels(CDCC) method with a ^(10)Be(0^+) + n two-body cluster model is applied to systematically analyze the elastic scattering of the halo nucleus ^(11)Be from the proton target at various incident energies below 100 MeV/nucleon.Using the renormalized ^(10)Be- p potential deduced from the ^(10)Be+ p elastic scattering data, the differential cross sections of ^(11)Be + p scattering are well reproduced by the CDCC calculations without any further adjustment parameters, demonstrating the applicability of this approach for describing the scattering of exotic nuclei based on the scattering of the less exotic core nuclei.
An overall irradiation and calibration technique was introduced and applied to a test scintillation detector array. An integral conversion method was used to reduce the nonlinearity of the time difference spectrum, and to improve the position determination especially for positions close to the two ends of a long scintillation bar. An overall position resolution of about 3.0 cm (FWHM) was extracted from the residual analysis method and verified by a direct measurement. Energy calibration was also realized by selecting cosmic rays at different incident angles. The bulk light attenuation lengths for the four test bars were also determined. It is demonstrated that these methods are especially efficient for calibrating large and complex detector arrays.
