Data on intrinsic conversions with pair formation were used in studies of energy transitions exceeding 2 nc-. Such transitions pass through an energy - slit." The energy levels of W/sup 182/ are plotted and transitions between rotation bands with K = 2/sup -/ and K = 0/sup -/ are analyzed. The spectra of pair conversion positrons and electrons were measured with a beta spectrometer using an irradiated tantalum oxide source. The resolving power was 1.8%. The data on transition multiplicity show that for 1122 kev the ( GAMMA / alpha K) x is in good agreement with E2 with a slight admixture Ml. The transition at 1188 kev is mixed 75% El + 25% M2. The 1222 kev transition is E2, which agrees with published data. The 1231 kev transition is E2 with a small admixture Ml. An El assigned to 1256 kev differs from that calculated, indicating a large error in determining the K line. The data for the 1275 kev transition indicate mixed transitions. This agrees with previous data when the mixture is 80% El + 20% M2. The multiplicity of the 1290 kev transition was found to be of M2 and E3 type or even higher. Previous data for 1290 kev show the relative intensity 5 plus or minus 2, while the obtained data indicate 3.3 for the M2 and 10.2 for E3. (R.V.J.)
