“…The ββ decay of 136 Xe results in an ionized Ba daughter. This has been an intriguing system, with efforts by both the nEXO (151,152) and NEXT (153) collaborations to identify single Ba ions with high efficiency. This technique still presents significant challenges to implementation, but the implication for positive identification of a ββ decay and the background rejection capabilities are significant enough to motivate continued development for deployment in future experiments.…”

Keywords lepton-number violation, neutrinos, beyond the Standard Model AbstractNeutrinoless double-beta decay is a forbidden, lepton-number-violating nuclear transition whose observation would have fundamental implications for neutrino physics, theories beyond the Standard Model and cosmology. In this review, we summarize the theoretical progress to understand this process, the expectations and implications under various particle physics models, as well as the nuclear physics challenges that affect the precise predictions of the decay half-life. We will also provide a synopsis of the current and future large-scale experiments that aim at discovering this process in physically well-motivated half-life ranges.

“…A schematic of the method is included in Figure 1. We argue that single atom sensitivity is feasible with the SAM, noting that single atom detection of Barium atoms in solid Xenon has been demonstrated [11,12]. The main advantage of this approach is that the detection mechanism is not affected by traditional background sources.…”

In this paper we propose a new method for measuring the cross section of low yield nuclear reactions by capturing the products in a cryogenically frozen noble gas solid. Once embedded in the noble gas solid, which is optically transparent, the product atoms can be selectively identified by laser induced fluorescence and individually counted via optical imaging to determine the cross section. Single atom sensitivity by optical imaging is feasible because the surrounding lattice of noble gas atoms facilitates a large wavelength shift between the excitation and emission spectrum of the product atoms. The tools and techniques from the fields of single molecule spectroscopy and superresolution imaging in combination with an electromagnetic recoil separator, for beam and isotopic differentiation, allow for a detection scheme with near unity efficiency, a high degree of selectivity, and single atom sensitivity. This technique could be used to determine a number of astrophysically important nuclear reaction rates.
