(Anti)Hydrogen Spectroscopy*
Hydrogen 1s2s Saturation Intensity Is = 0.9 W/cm2
Excitation Rate Re = 4p*84*(I/W/s*cm2)2/Dn/Hz
Photo Ionization Rate Rp = 9*I/W/s*cm2
Zeeman shift dnZ = 9.3*B Hz/T
ac Stark shift dnac = 1.7*I Hz /W*cm2
Velocity at 1mK V1K = 4 m/s
Timeofflight broadening DnTOF= 3 kHz (1 mK, 600 mm beam diam.)
Lyman a detection efficiency 106 = * effMCP (= 104 * 102)
1011 Hatoms (MIT Bose condensation)dn/n1s2s = 1013(1s integration time)
Just one Problem: Lymana detection via field quenching => atoms can be used once only
(all 1s, mF states get equally populated)
Antihydrogenexperiments benefit from
more particles
