摘要

Here we report on observing losses of thulium atoms from optical dipole trap at different magnetic fields. Loss spectra in range of 0 - 24 G magnetic fields were obtained at two temperatures of 2.2 and 12 mu K with 14 mG resolution. The spectrum at higher temperature has richer structure showing the appearance of new Fano-Feschbach resonances.
