ResumoThe emission spectrum of an evaporated lithium target has been investigated in the spectral region extending from 60 to 600 A. The intensity distribution of the characteristic $K$ emission band has been determined photometrically. Some features of the distribution $\frac{I(E)}{{\ensuremath{\nu}}^{2}}$ are as follows: the band has a maximum at 54.02 ev (229.50 A); the distribution drops to one-half of its maximum value on the high-energy side at 54.58 ev; and the decay in intensity from the peak to the high-energy limit of the band occurs in an energy interval of 1.18 ev. In agreement with the results of earlier investigators, the band does not show a sharp high-energy cutoff. A second band, similar in shape and having a maximum at 82.83 ev, has been observed and is presently identified as a $K$ satellite.
