RESONANCE SCATTERING BY Ni$sup 60$ $gamma$ QUANTA (in Russian)
A single-crystal luminescence spectrometer with a NaI(T1) crystal was used in studies of gamma radiation produced by neutron capture in iodine and neodymium isotopes. The g lines with energies of 28 plus or minus 2, 135 plus or minus 3, and l58 plus or minus 4 kev were found in the I/sup 128/ spectrum at 20 to 400 kev. The intensities (in captured neutron %) were 23 plus or minus 6, 20 plus or minus 4, and 7.5 plus or minus 1.5, respectively. The most probable multiplicity transitions were found to be E2 for 135 kev and M2 for 158 kev. The measurements on Nd were made with a Nd/sub 2/O/sub 3/ target. The energies of the gamma lines were measured for mixed Nd isotopes and for Nd/sup 144/. The gamma lines at 330 kev and part of the 445 and 610 kev lines belong to Sm/sup 150. The gamma lines 695 and 445 kev were related to Nd/sup 144/ and Nd/sup 146/ transitions from the initial state to the ground state. The existence of formerly unknown second excitation states at 1535 and 1055 kev, which emit the 840 and 640 kev gamma quanta, is assumed. Moreover, the relations of the energies of these states to the initial levels of E/sub 2/E/sub 1/ = 2.2 to 2.4 are inherent to to the oscillation levels of spherical even-even nuclei. (R.V.J.)
