The invariant-mass spectrum of $e^+ e^-$ pairs produced in $^{12}$C+$^{12}$C collisions at an incident energy 2 GeV per nucleon has been measured for the first time. pair production probabilities span over five orders magnitude from $\pi^0$-Dalitz to $\rho/\omega$ region. Dalitz decays $\pi^0$ and $\eta$ account all yield up 0.15 GeV/c$^2$, but only about 50% above this mass. A comparison with model calculations shows that excess is likely due baryon-resonance vector-meson decays. Transport...
By means of $\ensuremath{\gamma}$-ray spectroscopy following (heavy ion, $\mathrm{xn}$) reactions, we have established a level scheme for the yrast states in $^{186}\mathrm{Hg}$ up to ${14}^{+}$ state. From spectrum conclude that makes rather sudden angular-momentum-induced change deformation from small values at low spins large higher spins. This is qualitative agreement with several potential-energy surface calculations, and leads an interpretation previously measured isotopic shifts rms...
X rays emitted during the radiative capture of target electrons into $K$ shell fast and highly stripped projectiles were observed. When using targets with strongly bound electrons, a high-energy x-ray tail was also found; this new process is type electron bremsstrahlung. The cross sections for both these processes can be explained quantitatively.
Abstract Multimode fiber (MMF) sensors have been extensively developed and utilized in various sensing applications for decades. Traditionally, the performance of MMF was improved by conventional methods that focused on structural design specialty fibers. However, recent years, blossom machine learning techniques has opened up new avenues enhancing sensors. Unlike methods, do not require complex structures or rare fibers, which reduces fabrication difficulties lowers costs. In this review,...
To search for an |${\rm S} = -1$| di-baryonic state which decays to |$\Lambda p$|, the |${}^3{\rm He}(K^-,\Lambda p)n_{\rm missing}$| reaction was studied at 1.0 GeV}/c$|. Unobserved neutrons were kinematically identified from missing mass |$M_{X}$| of p)X$| in order have a large acceptance pn$| final state. The observed events, distributed widely over allowed region Dalitz plot, establish that major component comes three-nucleon absorption process. A concentration events specific neutron...
Absolute distance measurement is a field of research with large variety applications. Laser triangulation well-tested and developed technique using geometric relations to calculate the absolute an object. The advantages laser include its simple cost-effective setup yet high achievable accuracy resolution in short distances. A main problem technology that even small changes optomechanical setup, e.g., due thermal expansion, lead significant errors. Therefore, this work, we introduce optical...
First measurement of subthreshold \ensuremath{\Sigma}(1385) production is presented. Experimental data are presented for Al+Al reactions at $1.9A$ GeV measured with the FOPI detector SIS/GSI. The $\ensuremath{\Sigma}(1385)/\ensuremath{\Lambda}$ ratio found to be in good agreement transport and statistical model predictions. results allow a better understanding strangeness exchange reaction which dominant process ${K}^{\ensuremath{-}}$ below close-to threshold.
A variety of specialty fibers such as no-core fiber (NCF) have already been studied to reveal their sensing abilities. In this work, we investigate a fiber, square-core for temperature and strain sensing. simple single-mode-multimode-single-mode (SMS) sensor was fabricated, consisting 30-cm-long fiber. The experimental results indicate that the maximal wavelength-temperature wavelength-strain sensitivities are -15.3 pm/∘C -1.5 pm/με, respectively, while power-temperature power-strain 0.0896...
For applications where only moderate spectral resolution is required, static Fourier transform infrared spectrometers (sFTS) offer a comparatively cost-effective alternative to classical scanning instruments. In this paper, we present an sFTS based on single-mirror interferometer using standard optical components and uncooled microbolometer array. Because the instrument features concave mirrors rather than lenses, dispersion effects can be minimized. This enables broadband operation in...
