Query: Description of resonances in light nuclei using a microscopic cluster
  model   We investigate resonances in light halo nuclei using a fully microscopic
cluster model and the complex scaling method. We make use of the hermitian
representation of the complex scaling method. The general structure of the
cluster model is that of a correlation operator acting on a starting function
that describes a number of neutrons relative to an alpha-particle. The
correlation operator is expanded in terms of a small non-orthogonal set of
Gaussian basis states and we make use of a simplified, central but
state-dependent, interaction. The many-body integrals required for the
computation are evaluated by a variational Monte-Carlo algorithm. We show how
to obtain resonant states for both $^5$He and $^6$He.
