Abstract:We show that resonant enhanced
two-photon spectroscopy is a very powerful and promising diagnostic method for
trapped atomic hydrogen and antihydrogen. This method, in which photons of
different wavelengths are used to excite H atoms from thc IS to the 3D or 3S
level, uses the resonant enhancement of the intermediate 2P level to obtain
high sensitivity while at the same time offering potentially much higher
spectral resolution than single photon (Lyman-a) excitation.
