The determination of minerals in cocoa powder using laser-induced breakdown spectroscopy by Salimen, Nurfarhana, Abu Hanifah, Azimah, Munajat, Yusof

“…The peaks are identified by comparing their wavelengths with the Atomic Spectra Database (ASD) issued by the National Institute of Standards and Technology (NIST). …”

Measurement of Cyclic Variation of the Air-to-Fuel Ratio of Exhaust Gas in an SI Engine by Laser-Induced Breakdown Spectroscopy by Yuji Ikeda, Nobuyuki Kawahara

“…Optimum measurements performed between 200 ns and 10 ms after breakdown resulted in observed atomic spectra of CI (248 nm), H_β (485 nm), H_α (656 nm), NI (745, 824 nm), and OI (777, 844 nm). …”

Plasmono-atomic interactions on a fiber tip by Chan, Eng Aik, Adamo, Giorgio, Syed Abdullah Aljunid, Ducloy, Martial, Zheludev, Nikolay I., Wilkowski, David

“…Here, we show that an optical fiber sensor bearing a plasmonic metasurface at its tip can be used to detect modifications of the Doppler-free hyperfine atomic spectra induced by coupling between atomic and plasmonic excitations. …”

Classical and Quantum Spherical Pendulum by Richard Cushman, Jędrzej Śniatycki

“…The seminal paper by Niels Bohr followed by a paper by Arnold Sommerfeld led to a revolutionary Bohr–Sommerfeld theory of atomic spectra. We are interested in the information about the structure of quantum mechanics encoded in this theory. …”

Frequency measurement of 6s6p 3P0,2−6s7s 3S1 transitions in ultracold 171Yb atoms referenced to local optical clock by Hao Qiao, Chang-Yue Sun, Cheng-Quan Peng, Qi-Chao Qi, Cheng-Cheng Zhao, Min Zhou, Xin-Ye Xu

“…With the normalized shelving detection technique, about 12 MHz and 10 MHz linewidth of atomic spectra are obtained, respectively, which is some greater than the natural linewidth of 1.5 MHz and 5.9 MHz and is limited by the broadening from the probe and lattice light. …”
