“…And experiments are being conducted with high-intensity muon beams by various research groups like the HIPA at PSI [55], MUSE at J-PARC [56], TRIUMF, RAL, MuSIC at Osaka, etc. [57]. The novelty of this work lies in the fact that here we have performed a systematic calculation of the lowest bound state energy of exotic atoms and ions having nuclear charge ranging from Z = 2 to Z = 20.…”

Lowest bound S-state energy of Coulombic three-body systems ($N^{Z+}\mu^-e^-$) consisting of a positively charged nucleus of charge number $Z$ ($N^{Z+}$), a negatively charged muon ($\mu^-$) and an electron ($e^-$), is investigated in the framework of few-body (i.e., two- and three-body) cluster model approach. For the three-body cluster model, we adopted the hyperspherical harmonics expansion (HHE) method. An approximated two-body model calculation is also performed for all the three-body systems considered here. A Yukawa-type screened Coulomb potential with an arbitrary screening parameter ($\lambda$) is chosen for the two-body subsystems of the three-body system. In the resulting Schr"{o}dinger equation (SE), the three-body relative wave function is expanded in the complete set of hyperspherical harmonics (HH). The use of the orthonormality of HH in the SE leads to a set of coupled differential equations (CDEs) which are solved numerically for a manageable basis size to get the energy (E). The pattern of convergence in energy relative to increasing basis size is also investigated. Results are compared with some of those found in the literature.

“…X-ray spectroscopy is widely used in nuclear reaction and structure studies, as for example xray isotope shifts for nuclear charge distributions [1,2], the study of EC decay [3], mu-mesic atoms [4] and synchrotron processes [5], X-gamma-alpha coincidence spectroscopy for product Z identification in Super Heavy Nuclear synthesis [6] and x-ray bursts from thermonuclear processes in accreting neutron stars [7]. However, the most extensive area of the use of x-ray spectrometry in the nuclear sciences is in the quantitative analysis of trace elements in materials of importance to the nuclear industry and related areas.…”

X-ray spectroscopy is widely used in nuclear reaction and structure studies. To aid such studies the technological envelope is continually being pushed to achieve higher quality such as superior power and brilliance, higher resolution and sensitivity. We present the discussion of a relatively new form of X-ray fluorescence spectrometry - Total Reflection X-ray Fluorescence (TXRF) spectrometry that can achieve analytical sensitivities of the order of parts per billion (ppb). An overview of the TXRF technique is presented and its utility for nuclear materials analysis discussed. Polarized Energy Dispersive X-ray Fluorescence (PEDXRF) spectrometry is also an XRF technique that can complement TXRFS where it may not be applicable. That scenario is discussed with respect to our results using PEDXRF on geothermal samples that serve to corroborate the recent findings of the Borexino Geoneutrino Experiment regarding the high Th, U concentrations in the earth’s mantle.

“…Detailed simulations of the transfer reactions align with experimental data, indicating a solid grasp of the processes within the gas mixture. To validate this method, a measurement of the 2p-1s muonic x rays from a 5 μg gold target is presented as a proof of principle (Adamczak et al, 2023). The research presented highlights various aspects of muonic atoms, including their formation and behavior in different environments.…”

This study delves into the influence of muon positioning on particle behavior within atoms, exploring scenarios where the muon resides inside, outside, or partially inside the nucleus of a hydrogen atom. The observed behavior of the differential cross section (DCS) in these contexts yields significant insights into atomic interactions. When the muon is within the nucleus, a marked decrease in the DCS is noted as the electron's momentum undergoes changes. This suggests a substantial impact of the muon on scattering behavior, akin to phenomena in laser-assisted electron-hole scattering and classical scattering. Conversely, when the muon is outside the nucleus, a sharp decrease in DCS is observed at low momentum changes, in contrast to the behavior observed when the muon is within the nucleus. In cases where the muon is partially internal, an intermediary pattern emerges: exponential decay at lower energies and a gradual decline beyond 1.5 MeV. This behavior bridges the scenarios depicted with the muon inside and outside the nucleus. The findings underscore the pivotal role of muon placement in shaping scattering dynamics within atoms. This enhanced understanding of atomic interactions carries profound implications for the advancement of nuclear physics and our comprehension of the fundamental constituents of matter. The development and computational analysis of corresponding equations were facilitated through the MATLAB student package, bolstering the robustness of the study's conclusions.
