Intensities of Fe II lines were measured at a number of positions above the white light limb of the quiet sun, using photographic spectra obtained by the Naval Research Laboratory normal incidence spectrometer on Skylab. With the aid of experimental spontaneous decay rates previously published in the scientific literature we have calculated the spontaneous decay rates of over 550 Fe II transitions in the 2000-2800 A wavelength range. Two-hundred twenty of the measured spontaneous decay rates are published for the first time. It was determined that the Fe II levels in the solar chromosphere achieve a Boltzmann population corresponding to a about 0.78 eV temperature. The accuracy of the new rates is comparable to the accuracy of the previously published experimental rates.
