摘要：

Circular spectropolarimetry of the white dwarf G227-35 shows a prominent feature near 7450 angstrom, with a Stokes parameter jump DELTAV = + 0.05. We identify this with the stationary point in the 2p-1-3d-2 transition of Halpha, which has been calculated to be 7449.4 angstrom in a magnetic field of 117 MG. Other components of Halpha also are seen. A crude model which can explain the observations is a centered dipole seen close to pole-on, with a polar field strength of about 130 MG.
