Sguazzin M, Jurado B, Pibernat J, Swartz J, Grieser M, Glorius J, et al.
Phys Rev Lett . 2025 Mar; 134(7):072501. PMID: 40053944
Neutron-induced reaction cross sections of short-lived nuclei are imperative to understand the origin of heavy elements in stellar nucleosynthesis and for societal applications, but their measurement is extremely complicated due...

Nies L, Canete L, Dao D, Giraud S, Kankainen A, Lunney D, et al.
Phys Rev Lett . 2023 Dec; 131(22):222503. PMID: 38101393
Isomers close to doubly magic _{28}^{78}Ni_{50} provide essential information on the shell evolution and shape coexistence near the Z=28 and N=50 double shell closure. We report the excitation energy measurement...

Giovinazzo J, Roger T, Blank B, Rudolph D, Brown B, Alvarez-Pol H, et al.
Nat Commun . 2021 Aug; 12(1):4805. PMID: 34376669
Proton radioactivity was discovered exactly 50 years ago. First, this nuclear decay mode sets the limit of existence on the nuclear landscape on the neutron-deficient side. Second, it comprises fundamental...

Goigoux T, Ascher P, Blank B, Gerbaux M, Giovinazzo J, Grevy S, et al.
Phys Rev Lett . 2016 Oct; 117(16):162501. PMID: 27792367
In an experiment with the BigRIPS separator at the RIKEN Nishina Center, we observed two-proton (2p) emission from ^{67}Kr. At the same time, no evidence for 2p emission of ^{59}Ge...

Atanasov D, Ascher P, Blaum K, Cakirli R, Cocolios T, George S, et al.
Phys Rev Lett . 2015 Dec; 115(23):232501. PMID: 26684113
Masses adjacent to the classical waiting-point nuclide ^{130}Cd have been measured by using the Penning-trap spectrometer ISOLTRAP at ISOLDE/CERN. We find a significant deviation of over 400 keV from earlier...

Rosenbusch M, Ascher P, Atanasov D, Barbieri C, Beck D, Blaum K, et al.
Phys Rev Lett . 2015 Jun; 114(20):202501. PMID: 26047224
The recently confirmed neutron-shell closure at N=32 has been investigated for the first time below the magic proton number Z=20 with mass measurements of the exotic isotopes (52,53)K, the latter...

Orrigo S, Rubio B, Fujita Y, Blank B, Gelletly W, Agramunt J, et al.
Phys Rev Lett . 2014 Jun; 112(22):222501. PMID: 24949762
We report the observation of a very exotic decay mode at the proton drip line, the β-delayed γ-proton decay, clearly seen in the β decay of the T_{z}=-2 nucleus ^{56}Zn....

Ascher P, Audirac L, Adimi N, Blank B, Borcea C, Brown B, et al.
Phys Rev Lett . 2011 Oct; 107(10):102502. PMID: 21981498
The two protons emitted in the decay of 54Zn have been individually observed for the first time in a time projection chamber. The total decay energy and the half-life measured...

Proc Natl Acad Sci U S A . 2000 Oct; 97(21):11593-7. PMID: 11016958
At the cerebellar synapse between the parallel fibers (PFs) and the Purkinje cells in the cerebellum, we have found that application of N-methyl-d-aspartate (NMDA) reversibly depresses the postsynaptic current. We...
