The first excited states of 9 Be and 9 B
It is found here that the 1/2 + first excited state of 9 Be is a virtual state with the energy of-23.5 KeV. The line shape for the excitation of the state is approximated with a simple analytic form based on the effective range expansion. The partner in 9 B of this state is found to be a resonance with a maximum in the peak at about 1.1 MeV, FWHM of 1.5 MeV, and complex energy of 0.6 − i0.75 Me...
متن کاملStructure of the mirror nuclei 9 Be and 9 B
The structure of the mirror nuclei Be and B is studied in a microscopic α+ α+n and α+α+p three-cluster model using a fully antisymmetrized 9-nucleon wave function. The two-nucleon interaction includes central and spin-orbit components together with the Coulomb potential. The ground state of 9Be is obtained accurately with the stochastic variational method, while several particle-unbound states ...
متن کاملParticle decay of 12 Be excited states
The breakup of E/A = 50 MeV 12Be fragments following inelastic scattering off of hydrogen and carbon target nuclei has been studied. The breakup channels α+8He, 6He+6He, t + 9Li, and p+11Li were observed. Two doublets at excitation energies of 12.8 and 15.5 MeV were found for the α+8He channel. A low-energy shoulder in the excitation-energy spectra at 10.2 MeV indicates one or more additional s...
