Abstract: | <p>The independent quasi particle model of nuclear excited states has successfully been applied by previous authors to the N = 83 nuclei <sup>140</sup>La and <sup>142</sup>Pr. In both these nuclei configuration mixing between the(π1°g<sub>7/2</sub>ν2f<sub>7/2</sub>) and (π2°g<sub>5/2</sub>ν2f<sub>7/2</sub>) configurations is expected to produce 14 negative parity states with spins 0,1,1,2,2,3,3,4,4,5,5,6,6,7. In the case of <sup>140</sup>La all fourteen states have been identified among the low lying excitations (below 600 Kev). In <sup>142</sup>Pr previous research had placed 10 of the expected low lying states, and all of these were located below 200 kev.</p> <p>In our research, using data from <sup>139</sup>La (α,n) gamma-gamma coincidence, from <sup>141</sup>Pr (d,p), and <sup>144</sup>Nd (d,q), we were able to suggest the locations of three new nuclear levels in <sup>142</sup>Pr , two of which we believe to be the 6<sup>-</sup> cind 7<sup>-</sup> spin states not seen by previous investigators. The results are encouraging because these two levels are found at approximately the same excitation energy as the corresponding states in <sup>140</sup>La , and one hopes, therefore, that the similarity in level structure between these two nuclei can be explained by a neutron-proton interaction common to both nuclei. The three new states which we are suggesting are, [refer to the table in the pdf].</p> |
