Abstract
A detailed study of the L emission spectrum of thulium 69 has been made with the help of a 40 cm curved crystal spectrograph of the transmission type. As a result five diagram lines for this element have been measured and reported for the first time. The line λ 1441.20 X.U. corresponds to the dipole transition LIIIOI(β7), while the lines λ 1518.84 X.U. and λ 1497.32 X.U. correspond to the octupole and quadrupole transitions LIIMV and LIIINII, respectively. The remaining two new lines λ 1230.59 X.U. and λ 1341.15 X.U. are due to the non-quadrupole transitions LIOI and LIINII, respectively. Four transitions, viz. LIIOIV(γ6), LIMIV(β10), LIMV(β9) and LIOIV,V already reported only by Sakellaridis have been confirmed. However, the lines LIIIOIV,V(β5) and LIIIMI(l) also reported only by Sakellaridis could not be confirmed. The energy of the OI level of thulium has been re-evaluated.Keywords
