摘要：

The 90° cross section for the reaction 89Y(p,γo)90Zr has been measured for proton energies between 2.6 and 19.0 MeV using Van de Graaff protons and a Nal counter. Some angular distributions were also measured. There is no evidence of a well-defined component of the dipole resonance with T = T3 + 1 = 6. At low energies, the excitation function is in agreement with a statistical calculation of the Hausser-Feshbach type. At higher energies, there is a direct" component showing strong electric quadrupole interference. © 1969."
