First observation of long-lived $\pi^+ \pi^-$ atoms / DIRAC Collaboration
After observing and investigating the double-exotic $\pi^+\pi^-$ atom with the ground state lifetime $\tau$ of about $3 \times 10^{-15}$~s, the upgraded DIRAC experiment at the CERN PS accelerator observes for the first time long-lived states of the same atom with lifetimes of about $10^{-11}$~s and more. The number of characteristic pion pairs resulting from the breakup (ionisation) of long-lived $\pi^+\pi^-$ atoms amounts to $436\pm61$, corresponding to a signal-to-error ratio of better than 7 standard deviations.

Updated DIRAC spectrometer at CERN PS for the investigation of ππ and πK atoms / PS212 collaboration
The DIRAC spectrometer installed at CERN PS was redesigned and upgraded in order to study simultaneously Aππ and AπK atoms, namely the bound states of π+π–, and π+K–, π–K+ mesons. The detector system which is able to accept a high intensity beam such as 2 - 6 × 1011 primary protons per second, the electronics and the data-acquisition system adapted to handle very large amount of data actually allowed to identify successfully π, K, p, e and µ and to give the possibility to select π-π and π-K pairs in the off-line analysis. [...]

First $\pi K$ atom lifetime and $\pi K$ scattering length measurements / DIRAC Collaboration
The results of a search for hydrogen-like atoms consisting of $\pi^{\mp}K^{\pm}$ mesons are presented. Evidence for $\pi K$ atom production by 24 GeV/c protons from CERN PS interacting with a nickel target has been seen in terms of characteristic $\pi K$ pairs from their breakup in the same target ($178 \pm 49$) and from Coulomb final state interaction ($653 \pm 42$).

Evidence for $\pi K$-atoms with DIRAC / Adeva, B. (Santiago de Compostela U., IGFAE) ; Afanasyev, L. (Dubna, JINR) ; Allkofer, Y. (Zurich U.) ; Amsler, Claude (Zurich U.) ; Anania, A. (INFN, Messina ; Messina U.) ; Benelli, A. (Zurich U.) ; Brekhovskikh, V. (Serpukhov, IHEP) ; Caragheorgheopol, G. (Bucharest, IFIN-HH) ; Cechak, T. (Prague, Tech. U.) ; Chiba, M. (Tokyo Metropolitan U.) et al.
We present evidence for the first observation of electromagnetically bound $\pi^\pm K^\mp$-pairs ($\pi K$-atoms) with the DIRAC experiment at the CERN-PS. The $\pi K$-atoms are produced by the 24 GeV/c proton beam in a thin Pt-target and the $\pi^\pm$ and $K^\mp$-mesons from the atom dissociation are analyzed in a two-arm magnetic spectrometer. [...]

First results using a new technology for measuring masses of very short-lived nuclides with very high accuracy : the MISTRAL program at ISOLDE / ISOLDE Collaboration
MISTRAL is an experimental program to measure masses of very short- lived nuclides (T$_{1/2}$ down to a few ms), with a very high accuracy (a few 10$^{-7}$). There were three data taking periods with radioactive beams and 22 masses of isotopes of Ne, Na*, Mg, Al*, K, Ca, and Ti were measured. [...]
