Ukita Física, Astronomía y Matemáticas Angular distributions for the inelastic scattering of 13.0 MeV deuterons on 104;106;108;110Pd were measuredwith the Sao Paulo Pelletron-Enge-Spectrograph facility in the range of 120 · µlab · 640. A Coulomb-NuclearInterference analysis, employing the Distorted Wave Born Approximation with the Deformed Optical Modelas transition potential, under well established global optical parameters, was applied to the first quadrupolarexcitations. The values of C = ±CL =±NL , the ratio of charge to isoscalar deformation lengths, and of (±NL )2 wereextracted through the comparison of experimental and predicted cross section angular distributions. The ratiosof reduced charge to isoscalar transition probabilities, B(EL) to B(ISL) respectively, are related to the square ofthe parameter C and were thus obtained with the advantage of scale uncertainties cancellation. For 104Pd, andpreliminary for 108Pd, the respective values of C = 1.18(3) and C = 1.13(4) reveal an enhanced contribution ofthe protons relative to the neutrons to the excitation, while a smaller effect is found for 106Pd, C = 1.06(3) andfor 110Pd, C = 1.07(3), in comparison with the value C = 1.00 expected for homogenous collective excitations. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46434517 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3A Vol.34 |
