Excited States of {sup 11}Be
The {sup 11}B({sup 7}Li,{sup 7}Be){sup 11}Be reaction at 57 MeV incident energy was used to explore the {sup 11}Be excitation energy spectrum at forward angles. Angular distributions were extracted for the transitions to the ground and to the states of {sup 11}Be at excitation energies of E*=0.32, 1.78, 2.69, 3.41, 3.89, 3.96, 6.05 MeV combined with the ground and the first excited state of {sup 7}Be. Also the SDR [1][2] oscillation mode was observed at E*=9.5 MeV and FWHM{approx}9 MeV and a new peak at E*=6.05 MeV and FWHM{approx}0.3 MeV was observed. QRPA calculations in the G-matrix representation are in progress in order to describe the continuum structure of {sup 11}Be. DWBA calculations have been started to evaluate transferred angular momenta both in the one step and in the two steps dynamical framework.
