摘要：

A variable is constructed for each tau decay channel which carries all the available information on the tau spin state. Its use allows a simple determination of the polarization with the maximal sensitivity for all final states. Further applications to the tau --> a1nu channel are discussed and it is shown that a sizeable improvement of the measurement can be achieved.
