High-precision mass measurements of exotic $^{95-97}$Ag isotopes close to the $N = Z$ line have been conducted with the JYFLTRAP double Penning trap mass spectrometer, with the silver ions produced using the recently commissioned inductively-heated hot cavity catcher laser ion source at the Ion Guide Isotope Separator On-Line facility. The atomic mass of $^{95}$Ag was directly determined for the first time. [...]

/ Plattner, P. (CERN ; Innsbruck U. ; Heidelberg, Max Planck Inst.) ; Wood, E. (Liverpool U.) ; Ayoubi, L. Al (Jyvaskyla U.) ; Beliuskina, O. (Jyvaskyla U.) ; Bissell, M.L.

Collinear laser spectroscopy was performed on the isomer of the aluminium isotope $^{26m}$Al. The measured isotope shift to $^{27}$Al in the $3s^{2}3p\;^{2}\!P^\circ_{3/2} \rightarrow 3s^{2}4s\;^{2}\!S_{1/2}$ atomic transition enabled the first experimental determination of the nuclear charge radius of $^{26m}$Al, resulting in $R_c$=\qty{3.130±.015}{\femto\meter}.

/ Kurpeta, J (Warsaw U.) ; Abramuk, A (Warsaw U.) ; Rząca-Urban, T (Warsaw U.) ; Urban, W (Warsaw U.) ; Canete, L (Surrey U.) ; Eronen, T (Jyvaskyla U.) ; Geldhof, S (Leuven U.) ; Gierlik, M (NCBJ, Swierk) ; Greene, J P (Argonne (main)) ; Jokinen, A (Jyvaskyla U.) et al.
Neutron-rich $^{119}$Pd nuclei were produced in fission of natural uranium, induced by 25-MeV protons. Fission fragments swiftly extracted with the Ion Guide Isotope Separation On-Line method were mass separated using a dipole magnet and a Penning trap, providing mono-isotopic samples of $^{119}$Pd.

The ground-state-to-ground-state $\beta$-decay $Q$-value of $^{135}\textrm{Cs}(7/2^+)\to\,^{135}\textrm{Ba}(3/2^+)$ was directly measured for the first time utilizing the Phase-Imaging Ion-Cyclotron Resonance (PI-ICR) technique at the JYFLTRAP Penning-trap setup. It is the first direct determination of this $Q$-value and its value of 268.66(30)\,keV is a factor of three more precise than the currently adopted $Q$-value in the Atomic Mass Evaluation 2016.

The JYFLTRAP double Penning trap at the Ion Guide Isotope Separator On-Line (IGISOL) facility has been used to measure the atomic masses of 13 neutron-rich rare-earth isotopes. Eight of the nuclides, $^{161}$Pm, $^{163}$Sm, $^{164,165}$Eu, $^{167}$Gd, and $^{165,167,168}$Tb, were measured for the first time. [...]

Proton-neutron pairing correlations in the self-conjugate nucleus $^{42}$Sc
/ Koszorus, Agota (Liverpool U.) ; Vormawah, Liam (Liverpool U.) ; Beerwerth, Randolf (Helmholtz Inst., Jena) ; Bissell, Mark (Manchester U.) ; Campbell, Paul (Manchester U.) ; Cheal, Bradley (Liverpool U.) ; Devlin, Charlie (Liverpool U.) ; Eronen, Tommi (Jyvaskyla U.) ; Fritzsche, Stephan (Helmholtz Inst., Jena) ; Geldhof, Sarina (Jyvaskyla U. ; Leuven U.) et al.
Collinear laser spectroscopy of the $N=Z=21$ self-conjugate nucleus $^{42}$Sc has been performed at the JYFL IGISOL IV facility in order to determine the change in nuclear mean-square charge radius between the $I^{\pi}=0^{+}$ ground state and the $I^{\pi}=7^{+}$ isomer via the measurement of the $^{42\mathrm{g},42\mathrm{m}}$Sc isomer shift. New multi-configurational Dirac-Fock calculations for the atomic mass shift and field shift factors have enabled a recalibration of the charge radii of the $^{42-46}$Sc isotopes which were measured previously.

The β -delayed triple- α particle decay of 12 B has been measured with a setup that favours coincidence detection. A broad state in 12 C, previously reported around 10 MeV, has been seen and its properties determined through R-matrix analysis of the excitation spectrum. [...]

advanced reactor systems” initiative. These new measurements include neutron inelastic scattering
from 23Na, Mo, Zr, and 238U, neutron capture cross sections of 238U, 241Am, neutron induced
fission cross sections of 240Pu, 242Pu, 241Am, 243Am and 245Cm, and measurements that explore
the limits of the surrogate technique. [...]

Beta-delayed neutron (DN) data, including emission probabilities, P-n, and energy spectrum, play an important role in our understanding of nuclear structure, nuclear astrophysics and nuclear technologies. A MOdular Neutron time-of-flight SpectromeTER (MONSTER) is being built for the measurement of the neutron energy spectra and branching ratios. [...]
