A three-dimensional raytracing code is used to examine the effects of
refraction compensation obtained by bending the target along the lasin
g axis. The simulations relate to an experiment conducted at Osaka Uni
versity, where germanium slab targets, curved along the target length,
were irradiated. At large curvatures the normally weak J = 0 --> 1, 1
96 Angstrom line dominated the signal. General agreement with experime
nt is obtained.
