Summary: This article reports on the experimental study of the decay of 53mFe, where for the first time, the weak E6 and M5 decay branches' sum-coincidence contributions have been quantified. The branching ratio and transition rate of M5 have also been revised. Shell model calculations suggest that the effective proton charge for high-multipole, E4 and E6, transitions is quenched to approximately two-thirds of the collective E2 value. Correlations between nucleons may explain this unexpected phenomenon.

Summary: The paper reviews the recent progress in describing isospin-symmetry breaking within the nuclear shell model and its applications to actual problems. The review covers the fundamentals of isospin formalism, experimental signatures of isospin-symmetry breaking effects, and the construction of accurate Hamiltonians. It highlights the implications of these developments in nuclear decay studies and nuclear astrophysics.

Summary: Proton-emission branches of the 10(+) isomer in the T-z = -1 nucleus Ni-54 have been imaged using ACTAR TPC at GANIL. The study determines the reduced transition strengths and effective charges for E4 transitions near N = Z Ni-56.

Summary: This study conducted an experiment at the GANIL/LISE3 facility to produce the 10+ isomer of 54Ni and measure its proton radioactivity decay branches. The experiment successfully detected and separated the proton signals from the implanted ion signals using the ACTAR TPC device. The results revealed the existence of two emission branches with their relative branching ratio.

Summary: This article reviews recent advances in the study of energy splitting between excited isobaric analogue states, discussing experimental developments and new approaches related to spectroscopy of the most proton-rich members of isobaric multiplets. The review highlights the significant impact of the shell-model in analyzing energy differences and interpreting them in terms of nuclear structure phenomena.

Summary: In an experiment conducted at the Radioactive Isotope Beam Factory at RIKEN, excited states in Zn-56 were populated by one-neutron removal from a Zn-57 beam impinging on a Be target. Three gamma rays were observed and tentatively assigned to a specific yrast sequence. Excitation-energy differences between levels in Zn-56 and its isobaric analogue states in Fe-56 were compared using large-scale shell-model calculations.

Summary: Proton radioactivity, discovered 50 years ago, is important for studying nuclear structure and has various theoretical approaches. Experimental measurements of proton emission branches from the isomeric state in Ni-54m show high angular momentum decays that can be theoretically approximated. In this study, two proton emission branches from the 10+ state isomer of 54mNi were reported using a new detector.
