High-Precision Structural Studies of the Antiproton Helium Atom $\overline{p}^{4}He^+$ by Observing Laser Resonances with $\Delta v = \Delta (n-l-1) = 2$ / Yamazaki, T ; Widmann, E ; Eades, John ; Kumakura, M ; Morita, N ; Torii, H A ; Hori, Masaki (CERN) ; Ishikawa, T ; Maas, F E ; Tamura, H et al.
Very weak laser resonances of unfavoured transitions $(n,l) \rightarrow (n+1,l-1)$ have been observed in metastable \={p}$^4$He$^+$ atoms by using a pulsed antiproton beam. The observed wavelengths (713.578 $\pm$ 0.006 nm for $l$ = 34 and 726.095 $\pm$ 0.004 nm for $l$ = 35), as well as those of the known favoured transitions, are to a few ppm accounted for by a recent variational calculation of Korobov, which includes the relativistic correction..

Observation of double resonant laser induced transitions in the $v = n - l - 1 = 2$ metastable cascade of antiprotonic helium-4 atoms / PS205 Collaboration
A new laser-induced resonant transition in the $v=n-l-1=2$ metastable cascade of antiprotonic $^4$He atoms has been found by using a double resonance technique. This was done by setting the first laser to the already known 470.724 nm resonance ($(n,l)=(37,34)\rightarrow (36,33)$), while the $(38,35)\rightarrow (37,34)$ transition was searched for with the second laser.

Laser-induced resonant transitions in the v=n-l-1=2 and 3 metastable cascades of antiprotonic $^{3}He atoms / PS205 Collaboration
Laser-induced resonant transitions in metastable antiprotonic ^3He atoms have been found. The observed transitions at wavelengths 593.388 \pm 0.001~nm and at 463.947 \pm 0.002~nm have been respectively ascribed to the (n,l)~=~(38,34)\,\rightarrow\,(37,33) and the (36 33)\,\rightarrow\,(35,32) transitions..

Isotope Effects on Delayed Annihilation Time Spectra of Antiprotonic Helium Atoms in Low-Temperature Gas / PS205 Collaboration
The delayed annihilation time spectra (DATS) of antiprotonic helium atoms have been studied in isotopically pure low temperature ^3He and ^4He gas at various densities. The DATS taken at 5.8~K and 400~mbar are very similar in shape except for i) a small difference in the time scale and ii) the presence of a distinct fast decay component in the case of ^3He [...]
