A multiparticle spin-trap isomer has been discovered in the proton-unbound nucleus 158
73Ta85. The isomer
mainly decays by γ-ray emission with a half-life of 6.1ð1Þ μs. Analysis of the γ-ray data shows that
the isomer lies 2668 keV above the known 9þ state and has a spin 10ℏ higher and negative parity. This
19− isomer also has an 8644(11) keV, 1.4(2)% α-decay branch that populates the 9þ state in 154Lu.
No proton-decay branch from the isomer was identified, despite the isomer being unbound to proton
emission by 3261(14) keV. This remarkable stability against proton emission is compared with theoretical
predictions, and the implications for the extent of observable nuclides are considered.

The upgrade of the ALICE TPC with GEMs and continuous readout
ALICE TPC collaboration (Institute of Physics Publishing, 2021)The upgrade of the ALICE TPC will allow the experiment to cope with the high interaction rates foreseen for the forthcoming Run 3 and Run 4 at the CERN LHC. In this article, we describe the design of new readout chambers ... -
Superconductor-Ferromagnet Tunnel Junction Thermoelectric Bolometer and Calorimeter with a SQUID Readout
Geng, Z.; Helenius, A. P.; Heikkilä, T. T.; Maasilta, I. J. (Springer, 2020)The superconductor-ferromagnet thermoelectric detector (SFTED) is a novel ultrasensitive radiation detector based on the giant thermoelectric effect in superconductor-ferromagnet tunnel junctions. This type of detector can ... -
Multiparticle azimuthal correlations in p-Pb and Pb-Pb collisions at the CERN Large Hadron Collider
ALICE Collaboration (American Physical Society, 2014)Measurements of multiparticle azimuthal correlations (cumulants) for charged particles in p-Pb at √sNN = 5.02 TeV and Pb-Pb at √sNN = 2.76 TeV collisions are presented. They help address the question of whether there is ... -
Jet evolution in a dense medium : event-by-event fluctuations and multi-particle correlations
Escobedo Espinosa, Miguel; Iancu, Edmond (Elsevier BV, 2017)We study the gluon distribution produced via successive medium-induced branchings by an energetic jet propagating through a weakly-coupled quark-gluon plasma. We show that under suitable approximations, the jet evolution ...
