Levels in Sm<SUP>148</SUP> fed in the decay of Eu<SUP>148</SUP>

The disintegration scheme of 54 d Eu148 has been studied using a six-gap &#946;-ray spectrometer, scintillatoin spectrometers and e-&#947;, &#946;+-&#947; and &#947;-&#947; coincidence techniques. Levels are established in Sm148 at energies (in keV) of 0(0+), 551(2+), 1162(3-), 1181(4+), 1595(5-), 1735(3,4+), 1896(3-), 1908(6+), 2035(4-), 2097(6+), 2147(5+), 2196(6+), 2215(5+), 2735(4,5-) and 2803((4,5)-). The spin assignments are based on measured multipolarities of the transitions, combined with the known spins of some of the levels established in our study of the decay of Pm148. A&#946;+-&#947; coincidence experiment established a weak position feed of (0.13&#177;0.04)% to the 1162 keV level and/or the 1181 keV level. The total decay energy of Eu148 is 3110&#177;50 keV
