Praseodymium has only one stable and naturally occurring isotope, <sup>141</sup>Pr. It is thus a mononuclidic element, and its standard atomic weight can be determined with high precision as it is a constant of nature. This isotope has 82 neutrons, a magic number that confers additional stability.

We use crystal from scientific materials corporation. Parameters of YSO.

Praseodymium has only one stable and naturally occurring isotope, 141Pr. It is thus a mononuclidic element, and its standard atomic weight can be determined with high precision as it is a constant of nature. This isotope has 82 neutrons, a magic number that confers additional stability.

Crystal concentration Dimensions SN
Pr:YSO 0.005% 2x3x10 mm 3-468-37

Absorption

We have measure absorption of the crystal along the longest axis. Conditions: Tplate=3.26K, Tsample=3.3K, etalon length 50 cm.
