The angle dependence of the absorption has been measured for s- and
p-polarized light with high-contrast frequency-doubled Ti:sapphire
laser pulses of 150 fs duration and a mean intensity of 
W/cm2. With obliquely incident p-polarized laser light an
absorption of up to 62% is measured. The results are discussed on the
basis of hydrodynamic and PIC simulations. We find that resonance
absorption is the main absorption mechanism.
