Coulomb nuclear interference with deuterons in even palladium isotopes

Abstract

, the ratio of charge to isoscalar deformation lengths, and of (δ N L ) 2 were extracted through the comparison of experimental and predicted cross section angular distributions. The ratios of reduced charge to isoscalar transition probabilities, B(EL) to B(ISL) respectively, are related to the square of the parameter C and were thus obtained with the advantage of scale uncertainties cancellation. For 104 Pd, and preliminary for 108 Pd, the respective values of C = 1.18(3) and C = 1.13(4) reveal an enhanced contribution of the protons relative to the neutrons to the excitation, while a smaller effect is found for 106 Pd, C = 1.06(3) and for 110 Pd, C = 1.07(3), in comparison with the value C = 1.00 expected for homogenous collective excitations.

Single neutron pick-up on 104Pd

“…Among those, several have been put forward by investigations performed by the S. Paulo Nuclear Spectroscopy with Light Ions Group [1][2][3][4][5][6].…”
