/ Ali, Sk M (Bose Inst., Kolkata) ; Gupta, D (Bose Inst., Kolkata) ; Kundalia, K (Bose Inst., Kolkata) ; Saha, Swapan K (Bose Inst., Kolkata) ; Tengblad, O (Madrid, Inst. Estructura Materia) ; Ovejas, J D (Madrid, Inst. Estructura Materia) ; Perea, A (Madrid, Inst. Estructura Materia) ; Martel, I (U. Grenoble Alpes ; TIMA, Grenoble) ; Cederkall, J (Lund U.) ; Park, J (Lund U.) et al.
The Big Bang Nucleosynthesis (BBN) theory has been very successful in predicting the observed abundances of light elements like $^2$H, ${3,4}$He. There is, however, a serious discrepancy of a factor of about four in the observed abundance of $^7$Li as compared to that predicted by the BBN theory [1−2]. [...]

Stray-light Suppression for the MIRACLS Proof-of-principle Experiment
/ Lagaki, V (CERN ; Greifswald U.) ; Fischer, P (Greifswald U.) ; Heylen, H (CERN) ; Hummer, F (Linz U.) ; Lechner, S (CERN ; TU Vienna) ; Sels, S (CERN) ; Maier, F (Linz U.) ; Plattner, P (CERN ; Innsbruck U.) ; Rosenbusch, M (Greifswald U.) ; Wienholtz, F (CERN ; Greifswald U. ; Darmstadt, Tech. U.) et al.
The Multi-Ion Reflection Apparatus for Collinear Laser Spectroscopy
(MIRACLS), currently under development at ISOLDE/CERN, aims to
combine the high resolution of fluorescence-based collinear laser spectroscopy (CLS) with a high sensitivity. This will be achieved by confining
30-keV ion bunches in a Multi-Reflection Time-of-Flight (MR-ToF) device
which allows laser spectroscopic probing for several thousand times. [...]

The neutron-deficient $^{115}$Cs was produced at ISOLDE, CERN by spallation reaction using 1.4 GeV proton on LaC2 target. The exotic decay modes were studied by using a charged particle array (DSSD and pad detectors) and a γ-detector array (four Clovers) at the ISOLDE decay station (IDS). [...]

Phys.) ; Fynbo, H O U (Aarhus U.) ; Gad, A (Aarhus U.) ; Jensen, J (Aarhus U.) et al.
The main goal of this work is to study the structure of the highest energy states in $^8$Be populated following the $\beta^+$-decay and the electron capture (EC) of $^8$B. With this aim, two experiments were performed at ISOLDE-CERN in 2017 and 2018. [...]

$^{208}$Po populated through EC/β$^{+}$ decay
/ Brunet, M (Surrey U.) ; Berry, T A (Surrey U.) ; Podolyák, Zs (Surrey U.) ; Carroll, R J (Surrey U.) ; Lica, R (CERN ; Bucharest, IFIN-HH) ; Sotty, Ch (Bucharest, IFIN-HH ; Leuven U.) ; Andreyev, A N (York U., England) ; Borge, M J G (CERN) ; Cubiss, J G (CERN ; York U., England) ; Fraile, L M (Madrid U.) et al.
The structure of $^{208}$Po resulting from the EC/β + decay of $^{208}$At was studied at CERN’s ISOLDE Decay Station (IDS). The high statistics afforded by the high yield of $^{208}$At and the high efficiency HPGe clusters at the IDS allowed for greater insight into lower intensity transitions and thus significant expansion of the $^{208}$Po level scheme.
