The reaction He-4(<(gamma)over right arrow>,pi(0))He-4 has been studied wit
h the LEGS tagged, polarized gamma-ray beam, Data are presented at laborato
ry angles of 31 degrees, 45 degrees, 72.5 degrees, 90 degrees, 110 degrees
and 130 degrees for incoming photon energies of 206, 219, 232, 245, 259, 27
4, 289, 306 and 322 MeV. The unpolarized cross sections are compared with t
he Delta-hole theoretical model results available in literature. The measur
ed photon beam asymmetry is -1 as expected from conservation of angular mom
entum and parity. (C) 1999 Published by Elsevier Science B.V.
