Single-colour resonance three-photon ionization of samarium atoms

Abstract: Single-colour resonance three-photon ionization of Sm atoms is studied within the 542.4-581.6 nm spectral range. Wavenumber dependence of the Sm + ion yield shows more than 600 maxima of different amplitudes and shapes. Most of the resonance structure observed is due to two-photon excitation of even-parity bound states lying in the 34 713.1-40 526.7 cm −1 energy range. Fifteen new even-parity bound states have been found. Their energies and total momenta have been determined.

“…The superscripts ("a-i") in the table denote levels that were previously observed in [6][7][8][9][10][11][12][13][14][15][16]. Comparison of the energy values measured in this work with the data of other authors shows that they are in good agreement with each other.…”

“…The studies were conducted using the experimental arrangement described in detail in [7]. The output of an FL 2001 pulsed tunable dye laser (Lambda Physik) with a linewidth of ~0.2 cm -1 was focused into a vac uum chamber where it crossed an atomic beam of samarium at the right angle.…”

“…Одним з факторів, який обмежує ефективне використання методу одноколірної трифотонної резонансно-іонізаційної спектроскопії високозбуджених парних станів атома самарію, є те, що не всі можливі двофотонні переходи, що дозволені правилами відбору, чітко проявляються у вигляді резонансних максимумів у спектрах трифотонної іонізації, виміряних при певному значенні інтенсивності лазерного випромінювання [11]. Йдеться про двофотонні переходи, яким відповідають максимуми малої амплітуди.…”
