Scientific paper

We present excited meson masses from quenched calculations using chirally
improved (CI) quarks at pion masses down to 350 MeV. The salient features of
our analysis are the use of a matrix of correlators from various source and
sink operators and a basis which includes quark sources with different spatial
widths, thereby improving overlap with states exhibiting radial excitations.
