Abstract
The and spectra are investigated in a microscopic three-cluster model, using the generator-coordinate method. Both nuclei are described by a core surrounded by a nucleon. We present the nBe and pBe phase shifts, and the electromagnetic transition probabilities in . A good overall agreement is found with the available experimental data. We suggest spin assignments for different poorly known states. The energy of the first excited state in is in excellent agreement with a recent experimental investigation.
