Electron-positron angular correlations were measured for the isovector magnetic dipole 17.6 MeV (${J}^{\ensuremath{\pi}}={1}^{+}$, $T=1$) $\text{state}\ensuremath{\rightarrow}\text{ground}$ state (${J}^{\ensuremath{\pi}}={0}^{+}$, $T=0$) and isoscalar 18.15 transitions in $^{8}\mathrm{Be}$. Significant enhancement relative to internal pair creation was observed at large angles correlation transition with a confidence level of $>5\ensuremath{\sigma}$. This observation could possibly be due...
The β feeding probability of Tc102,104,105,106,107, Mo105, and Nb101 nuclei, which are important contributors to the decay heat in nuclear reactors, has been measured using total absorption technique.

The question, whether the high-quality nucleon-nucleon potentials can successfully describe three-nucleon system, and to what extent forces (3NFs) play a role, has become very important in nuclear few-body physics. One kinematic region where effects because of 3NFs show up is minimum differential cross section elastic nucleon-deuteron scattering. Another observable, which could give an indication about contribution spin 3NFs, vector analyzing power. To investigate importance systematically...
To investigate the importance of three-nucleon forces (3NF) systematically over a broad range intermediate energies, differential cross sections elastic proton-deuteron scattering have been measured at proton bombarding energies 108, 120, 135, 150, 170, and $190\phantom{\rule{0.3em}{0ex}}\text{MeV}$ c.m. angles between $30\ifmmode^\circ\else\textdegree\fi{}$ $170\ifmmode^\circ\else\textdegree\fi{}$. Comparisons with Faddeev calculations show unambiguously shortcomings employing only two-body...
Low‐dimensional copper halides with perovskite–analogue structure are a rapidly growing material family for light‐emitting and X‐ray screening devices. Among them Cs 3 Cu 2 I 5 exhibits exceptional optoelectronic properties (large Stokes shift, high emission yield), due to the strong confinement effect of its 0D structure. However, radioluminescence response energetic ions has only marginally been explored heavy fully ignored detrimental luminescence quenching. Herein, scintillation thin...
Sharp transmission resonances have been observed in the $^{235}U(d,pf)^{236}U$ reaction.

The β-feeding probabilities for three important contributors to the decay heat in nuclear reactors, namely 102,104,105Tc, have been measured using total absorption spectroscopy technique. For measurements, sources of very high isobaric purity obtained a Penning trap (JYFLTRAP). A detailed description data analysis is given and results are compared with high-resolution measurements theoretical calculations.16 MoreReceived 23 October 2012DOI:https://doi.org/10.1103/PhysRevC.87.044318©2013...
Abstract Herein, the first study on scintillation properties of CsCu 2 X 3 and Cs Cu 5 (where X: Cl − , Br I ) is presented, describing their charged particle‐induced luminescence involving electrons, protons, α‐particles, heavy ions, as well revealing capabilities timing spectroscopic evaluation single‐particle events. The thin layers are prepared with a simple cost‐effective deposition procedure, without incorporation external dopants, exploiting intrinsic radiative recombination observed...
The ${}^{51}\mathrm{V}{(d,}^{2}\mathrm{He}{)}^{51}\mathrm{Ti}$ charge-exchange reaction has been investigated at an incident energy of 171 MeV and scattering angles near $0\ifmmode^\circ\else\textdegree\fi{}.$ two protons in the ${}^{1}{S}_{0}(\mathrm{pp})$ state (denoted as ${}^{2}\mathrm{He})$ were both momentum analyzed detected by same spectrometer detector.

The two-neutrino double-$\ensuremath{\beta}$ $(2\ensuremath{\nu}\ensuremath{\beta}\ensuremath{\beta})$ decay represents a test case for our knowledge about the nuclear structure of involved isobars. $^{48}\mathrm{Ca}$ is an especially interesting because it holds anomaly uniquely high ${Q}_{\ensuremath{\beta}\ensuremath{\beta}}$ value and comparatively long half-life, which points to peculiar situation. matrix element relevant $\ensuremath{\beta}\ensuremath{\beta}$ can be calculated, if...
A new experimental approach to the famous problem of anomalously slow Gamow-Teller (GT) transitions in β decay A=14 multiplet is presented. The GT strength distributions excited states 14C and 14O were studied high-resolution (d,2He) (3He,t) charge-exchange reactions on 14N. No-core shell-model calculations capable reproducing suppression decays predict a selective excitation Jπ=2+ states. confirmation represents validation assumptions about underlying structure 14N ground state wave...

Here, $^{116}\mathrm{In}$ is intermediate nucleus in second-order perturbative description of $^{116}\mathrm{Cd}$ double beta $(\ensuremath{\beta}\ensuremath{\beta})$ decay.

Electron-positron angular correlations were remeasured for the 17.6 MeV (Jπ = 1+ → 0+) ground state transition in 8Be using an improved setup compared to one we used previously. Significant deviations from internal pair creation was observed at large angles correlations, which supports that, intermediate step, a neutral isoscalar particle with mass of 17.0 ±0.2(stat) ±0.5(sys) MeV/c2 and Jπ 1+was created.
A recoil coincidence technique has been applied to measure the alpha-decay branching ratios of near-threshold states in 19Ne. Populating these using (p,t) reaction inverse kinematics, we detected recoils and their decay products with 100% geometric efficiency a magnetic spectrometer. Combining our ratio measurements independent determinations radiative widths states, calculate astrophysical rate 15O(alpha,gamma)19Ne. Using this rate, perform hydrodynamic calculations nova outbursts conclude...
