A ps UV laser pulse was used to irradiate solid slab targets at intensity {ital l}=10{sup 14}{approximately}10{sup 16} W/cm{sup 2}. Anisotropy of the electron distribution function was measured by x-ray polarization spectroscopy. Even with time-integrated measurements, the strong polarization of {ital F} 1{ital s}{sup 2}{minus}1{ital s}2{ital p}({sup 1}{ital S}) line was observed at lower intensity condition. It denoted that the beam-like electrons generated at the interaction region penetrated into the over-density critical region. {copyright} {ital 1996 American Institute of Physics.}
