The emission spectra of /sup 254/Es and /sup 250/Bk have been studied by the methods of semiconductor alpha, gamma, and x-ray spectrometry. The results of the determination of the intensities of the gamma rays of /sup 254/Es at 63, 85, 290, and 385 keV have been presented: 1.6 /plus minus/ 0.4, 0.16 /plus minus/ 0.7, 0.3 /plus minus/ 0.1, and 0.4 /plus minus/ 0.1%, respectively. The ratio of the intensities of the gamma rays of /sup 250/Bk at 988.96 keV and at 1028.58 and 1031.76 keV has been calculated and found to be equal to 1.113 /plus minus/ 0.0037. The intensities of the x-rays of /sup 250/Bk of the L/sub 3/, L/sub /alpha//, L/sub /beta//, and L/sub /gamma// series form a 6:87:100:21 ratio. The half periods have been determined: /sup 254/Es, 266 /plus minus/ 4 days; /sup 250/Bk, 186.2 /plus minus/ 1.1 min.
