First measurement of the Lyman-alpha lines of anti-hydrogen

Posted on 23/08/2018 by Jon Butterworth

The ALPHA experiment (no relation) at the CERN antiproton decelerator has just published the first measurement of the Lyman-alpha lines of anti-hydrogen (a positron bound to an antiproton)¹.  There is an excellent summary of the measurement here, written by Ana … Continue reading →
