Finding
This result is in excellent agreement with theoretical predictions, if the fine structure of hydrogen is taken into account.

Complete linear polarization of Lyman- alpha radiation from metastable hydrogen atoms in external electric fields.
Abstract
The linear Stark effect of hydrogen was investigated for the metastable H(2s) state measuring the degree of linear polarization of field-induced Lyman-\ensuremath{\alpha} radiation. For sufficiently large electric fields (few kV/cm) the measured degree of linear polarization P is almost complete (P\ensuremath{\approxeq}-100%). This result is in excellent agreement with theoretical predictions, if the fine structure of hydrogen is taken into account.
