“…[1][2][3][4] Precision measurements of forbidden transitions have multiple applications, including probing fundamental physics, [5][6][7][8][9][10] developing frequency-standard metrology, [11][12][13][14] and searching for new physics beyond the standard models. [15] Moreover, these forbidden lines contribute significantly to diagnosing laboratory and astrophysical plasmas, [1,[16][17][18][19][20] since their intensities tend to be sensitive to the density or temperature of the plasma.…”
