Variations in the charge radii of indium isotopes between $N$ = 52 and 82
/ CRIS-ISOLDE Collaboration
Measurements of the 5$\mathrm{p}$ $^2P_{3/2}$ $\to$ $9_s$ $^2 S_{1/2}$ and 5$\mathrm{p}$ $^2P_{1/2}$ $\to$ $8_s$ $^2 S_{1/2}$ transitions in the indium atom, combined with new atomic physics calculations, were used to extract the changes in mean-square nuclear charge radii, $\delta$($r^2$), of the indium (Z = 49) isotopes $^{101-111}$In, $^{113-123}$In, and $^{125-131}$In. With a proton hole in the closed nuclear shell of Z = 50, indium provides a detailed study of the effect of unpaired nucleons adjacent to the proton-shell closure, allowing investigation into the charge radii for isotopes between the two major neutron-shell closures at N = 50 and N = 82.

Measurement of the natC(n,p) and natC(n,d) reactions from n_TOF at CERN
/ n_TOF Collaboration
The energy dependence of the cross section of the (n,p) and (n,d) reactions on $^\text{nat}$C has been studied for the first time at the n_TOF facility at CERN, from the particle detection threshold up to 25 MeV. The measurement was performed with two telescopes made of position-sensitive silicon $ΔE$-$E$ detectors, covering the angular range from 20° to 140°. [...]

Reduction in nuclear size and quadrupole deformation of high-spin isomers of $^{127,129}$In

(Leuven U.) ; Delaroche, J.P. (CEA DAM) ; Dobaczewski, J. (York U., England ; Warsaw U.) et al.
We employed laser spectroscopy of atomic transitions to measure the nuclear charge radii and electromagnetic properties of the high-spin isomeric states in neutron-rich indium isotopes (Z = 49) near the closed proton and neutron shells at Z = 50 and N = 82. Our data reveal a reduction in the nuclear charge radius and intrinsic quadrupole moment when protons and neutrons are fully aligned in 129In(N = 80), to form the high spin isomer. [...]

Charge radii of neutron-rich scandium isotopes and the seniority symmetry in the $0f_{7/2}$ shell
/ Bai, S.W. (Peking U., SKLNPT) ; Yang, X.F. (Peking U., SKLNPT) ; Koszorús, Á. (Leuven U.) ; Berengut, J.C. (New South Wales U.) ; Billowes, J. (Manchester U.) ; Bissell, M.L. (Manchester U.) ; Blaum, K. (Heidelberg, Max Planck Inst.) ; Borschevsky, A. (Groningen U.) ; Campbell, P. (Manchester U.) ; Cheal, B. (Liverpool U.) et al.
Nuclear charge radii of neutron-rich $^{47-49}$Sc isotopes were measured using collinear laser spectroscopy at CERN-ISOLDE. The new data reveal that the charge radii of scandium isotopes exhibit a distinct trend between $N=20$ and $N=28$, with $^{41}$Sc and $^{49}$Sc isotopes having similar values, mirroring the closeness of the charge radii of $^{40}$Ca and $^{48}$Ca.

Results of the $^{244}$Cm, $^{246}$Cm and $^{248}$Cm neutron-induced capture cross sections measurements at EAR1 and EAR2 of the n_TOF facility
/ nTOF Collaboration
Accurate neutron capture cross section data for minor actinides (MAs) are required to estimate the production and transmutation rates of MAs in light water reactors, critical fast reactors like Gen-IV systems, and other innovative reactor systems such as accelerator driven systems (ADS). In particular, 244Cm, 246Cm and 248Cm play a role in the transport, storage and transmutation of the nuclear waste of the current nuclear reactors, due to the contribution of these isotopes to the radiotoxicity, neutron emission, and decay heat in the spent nuclear fuel.

Detector set up for the measurements of the neutron-induced fission cross section of $^{235}$U relative to n-p scattering up to 150 MeV at CERN-n_TOF
/ Pirovano, E (Braunschweig, Phys. Tech. Bund.) ; Manna, A (INFN, Bologna ; U. Bologna, DIFA) ; Colonna, N (INFN, Bari) ; Console Camprini, P (INFN, Bologna ; ENEA, Bologna) ; Cosentino, L (INFN, LNS) ; Dietz, M (Braunschweig, Phys. Tech.

A new measurement of the $^{235}$U(n,f) fission cross section was carried out at n_TOF. The experiment covered the neutron energy range from 10 MeV up to 500 MeV, and it used the 1H(n,n) cross section as normalization for the neutron fluence measurement. [...]
