“…In most cases, the primary goal was to deduce the nuclear magnetic moments of the impurity isotopes [28]. The same technique is also used to ground state spins [29], hyperfine fields [1,30], nuclear relaxation times [31,32], and quadrupole splittings [33,34], as well as to obtain information on the lattice location and implantation behavior of implanted impurities [13,[35][36][37]. NMR/ON experiments require the nuclei to be oriented, which is done using the LTNO method [4] and requires cooling down the radioactive samples to temperatures in the millikelvin region and subjecting them to high magnetic fields, either hyperfine magnetic fields [4] or externally applied fields [38].…”

“…The magnetic hyperfine fields of substitutional impurities in bcc Fe are at present well understood for most of the elements in the periodic table [5][6][7][8][9][10][11], with sizeable differences between theory and experiment remaining mainly for the heavier 5d impurities [12,13], the alkaline elements [14][15][16][17], and the actinides [11]. Still, for a few elements no precise experimental results are available yet.…”

A new value for the hyperfine magnetic field of copper impurities in iron is obtained by combining resonance frequencies from experiments involving beta-NMR on oriented nuclei on Cu-59, Cu-69, and Cu-71 with magnetic moment values from collinear laser spectroscopy measurements on these isotopes. The resulting value, i.e., B-hf(CuFe) = -21.794(10) T, is in agreement with the value adopted until now but is an order of magnitude more precise. It is consistent with predictions from ab initio calculations. Comparing the hyperfine field values obtained for the individual isotopes, the hyperfine anomalies in Fe were determined to be (59)Delta(69) = 0.15(9)% and (71)Delta(69) = 0.07(11)%

“…For the low doses that are used in this type of measurements (i.e. typically of the order of 10 11 to 10 13 at cm −2 ) this two-site model is valid and high values for the fraction f can be achieved [162,163]. Further, v/c is the β-particle's initial velocity relative to the speed of light, P is the degree of nuclear polarization, Q takes into account the solid angle as well as effects of the magnetic field and scattering, and θ is the emission angle of the β-particle with respect to the magnetization (polarization) direction in the Fe foil.…”

The beta-decay process offers unique possibilities for testing the fundamental symmetries of the standard model and searching for non-standard model components in the weak interaction. Here a non-exhaustive review of this field is given highlighting a number of key experiments or recently performed experiments. Also included are new and ongoing developments providing new opportunities for further significant progress in this research field in the era of the large hadron collider.

Radioactive nuclei offer unique possibilities to study the structure and symmetries of the weak interaction in nuclear β decay. The large variety of nuclear states available allows selecting the ones that are best suited to study the phenomena of interest with optimal sensitivity, while at the same time minimising the effects of nuclear structure. The ISOLDE facility, offering worldwide the largest variety and intensity of radioactive beams, is one of the best suited laboratories in this respect. Over the last decade or so different aspects of the weak interaction have been studied at ISOLDE, ranging from half-lives, branching ratios and nuclear masses relevant for the determination of the V ud quark-mixing matrix element, over β-asymmetry and bn correlation measurements searching for possible tensor and/or scalar contributions to the weak interaction, up to a measurement showing the effect of parity violation in the weak interaction in gamma decay. In addition, new projects respectively searching for scalar currents in the β-delayed proton decay of 32 Ar, or to determine the V ud quark-mixing matrix element from the β-asymmetry parameter in the mirror decay of 35 Ar, have just started.
