225Pa and 221Ac were produced at the IGISOL facility through proton-induced fusion-evaporation reactions and have been studied using α-particle spectroscopy, as well as α−γ and α-electron coincidence spectroscopy. The level scheme of 221Ac, daughter of 225Pa, and of 217Fr, daughter of 221Ac were reconstructed. An interpretation of 221Ac levels as K=5/2± and K=3/2± parity-doublet bands is proposed. Such bands appear in reflection-asymmetric models and would be an indication of a static reflection asymmetric shape for 221Ac.

Constraining energy loss from high-pt azimuthal asymmetries
Andres, C.; Armesto, N.; Niemi, H.; Paatelainen, R.; Salgado, C. (Sissa Medialab srl, 2019)The nuclear modification factor RAA has been satisfactorily described by various jet quenching models. Nonetheless, all these formalisms, until very recently, underpredicted the high-pT (> 10 GeV) elliptic flow v2. We find ... -
