Al
clusters are studied with ab initio, many-body methods. Coupled-cluster theory places the icosahedral structure 0.54 eV lower than the D5h isomer. Electron propagator predictions on the photoelectron spectrum of Al
are in close agreement with the observed bands and attribute shakeup character to features at higher energy. ©1999 American Institute of Physics.
