Modeling the composition of neutron-star crusts depends strongly on binding energies neutron-rich nuclides near $N=50$ and $N=82$ shell closures. Using a recent development time-of-flight mass spectrometry for on-line purification radioactive ion beams to access more exotic species, we have determined first time $^{82}\mathrm{Zn}$ with ISOLTRAP setup at ISOLDE-CERN facility. With robust model based nuclear energy-density-functional theory, solve general relativistic...
Neutrinos, and in particular their tiny but non-vanishing masses, can be considered one of the doors towards physics beyond Standard Model. Precision measurements kinematics weak interactions, 3H β-decay 163Ho electron capture (EC), represent only model independent approach to determine absolute scale neutrino masses. The experiment, ECHo, is designed reach sub-eV sensitivity on mass by means analysis calorimetrically measured spectrum nuclide 163Ho. maximum energy available for this decay,...
Abstract New developments in liquid scintillators, high-efficiency, fast photon detectors, and chromatic sorting have opened up the possibility for building a large-scale detector that can discriminate between Cherenkov scintillation signals. Such could reconstruct particle direction species using light while also having excellent energy resolution low threshold of scintillator detector. Situated deep underground, utilizing new techniques computing reconstruction, this achieve unprecedented...
The recently confirmed neutron-shell closure at N = 32 has been investigated for the first time below magic proton number Z 20 with mass measurements of exotic isotopes 52,53K, latter being shortest-lived nuclide online spectrometer ISOLTRAP. resulting two-neutron separation energies reveal a 3 MeV shell gap 32, slightly lower than 52Ca, highlighting doubly-magic nature this nuclide. Skyrme-Hartree-Fock-Boguliubov and ab initio Gorkov-Green function calculations are challenged by new but...
Jinping Neutrino Experiment (Jinping) is proposed to significantly improve measurements on solar neutrinos and geoneutrinos in China Laboratory - a lab with number of unparalleled features, thickest overburden, lowest reactor neutrino background, etc., which identify it as the world-best low-energy laboratory.

The mean-square charge radii of $^{207,208}\mathrm{Hg}$ ($Z=80$, $N=127$, 128) have been studied for the first time and those $^{202,203,206}\mathrm{Hg}$ ($N=122$, 123, 126) remeasured by application in-source resonance-ionization laser spectroscopy at ISOLDE (CERN). characteristic kink in $N=126$ neutron shell closure has revealed, providing information on its behavior below $Z=82$ proton closure. A theoretical analysis performed within relativistic Hartree-Bogoliubov nonrelativistic...
We present an improved measurement of the carbon-nitrogen-oxygen (CNO) solar neutrino interaction rate at Earth obtained with complete Borexino Phase-III dataset. The measured rate, R_{CNO}=6.7_{-0.8}^{+2.0} counts/(day×100 tonnes), allows us to exclude absence CNO signal about 7σ C.L. correspondent flux is 6.6_{-0.9}^{+2.0}×10^{8} cm^{-2} s^{-1}, taking into account flavor conversion. use new evaluate C and N abundances in Sun respect H abundance for first time neutrinos. Our result...
In the search for nuclide with largest probability neutrinoless double-electron capture, we have determined Q(ϵϵ) value between ground states of (152)Gd and (152)Sm by Penning-trap mass-ratio measurements. The new 55.70(18) keV results in a half-life 10(26) yr 1 eV neutrino mass. With this smallest among known 0νϵϵ transitions, is promising candidate capture.
Among the short-lived radioactive nuclei inferred to be present in early solar system via meteoritic analyses, there are several heavier than iron whose stellar origin has been poorly understood. In particular, abundances for 182Hf (half-life = 8.9 million years) and 129I 15.7 disagreement with each other if both produced by rapid neutron-capture process. Here, we demonstrate that contrary previous assumption, slow process asymptotic giant branch stars produces 182Hf. This allowed us date...
The masses of the neutron-rich copper isotopes Cu75–79 are determined using precision mass spectrometer ISOLTRAP at CERN-ISOLDE facility. trend from new data differs significantly that previous results, offering a first accurate view surface adjacent to Z=28, N=50 nuclide Ni78 and supporting doubly magic character. compare very well with large-scale shell-model calculations predict shape coexistence in island inversion for Z<28. A coherent picture this important exotic region begins emerge...

We report the first measurement of CNO solar neutrinos by Borexino that uses Correlated Integrated Directionality (CID) method, exploiting sub-dominant Cherenkov light in liquid scintillator detector. The directional information origin is preserved fast photons from neutrino scattered electrons, and used to discriminate between signal background. independent spectral on which previous measurements were based.

A new approach (called COBRA) for investigating double beta decay using CdTe semiconductor detectors is proposed. This will allow simultaneous measurements of 5β−β−- and 4β+β+-emitters at once. Half-life limits neutrinoless 116Cd 130Te can be improved by more than one order magnitude sensitivities on the effective Majorana neutrino mass less 1 eV obtained. Furthermore, first time a realistic chance observing electron capture processes exists. Additional searches rare like 4-fold forbidden...
