Fine-structure measurement in the first excited state of positronium

Description

The 23S1-23P2 energy splitting of positronium has been observed by inducing rf transitions in a weak magnetic field (approx. =50 G) in the absence of a buffer gas and observing a resonant increase in the Lyman-α emission. We obtain 8628.4plus-or-minus2.8 MHz, which is within 2 standard deviations of the theoretical value computed to order α3R by Fulton and Martin
