TL;DR: In this paper, the authors evaluated single, coincidence and anticoincidence gamma-ray spectrometry methods with the aim of searching for double-electron capture of 74Se to excited states.

Abstract: For many years the International Atomic Energy Agency (IAEA) has been promoting analytical quality assurance and quality control in its Member States with emphasis on measurands that are amenable to analysis by nuclear and related techniques, i.e. radionuclides, trace elements, and stable isotopes. This paper reviews briefly the rationale for some of these activities, particularly in relation to the needs of participants in developing countries arising out of co-ordinated research programmes, technical co-operation projects and global and regional networks. Emphasis is given to biological and environmental reference materials with a matrix of natural origin. Also described are some activities arising out of the requirements of ISO-25 and other relevant international quality standards.

TL;DR: In this article , an experimental setup used at the CENTA (Centre for Nuclear and Accelerator Technologies) laboratory to carry out IBA (Ion Beam Analysis) techniques is described.

TL;DR: In this paper, the results obtained with three different detectors based on LiAlO_2, a target crystal never used before in cryogenic experiments, were presented with respect to spin-dependent dark matter interactions in the low mass region.
