The present work is devoted to study of spectroscopic aspects, in terms of neutron strength function, for the threshold effects with non-light nuclei. Relations to the neutron strength functions of the anomal effects observed at threshold of neutron

In this work we discuss kinematical and dynamical factors which could result in inhibition of the deuteron-stripping threshold effects. These effects are determined both by the reaction mechanism of (d, p) background reaction and by the strength func

The existence of loosely bound, spatially extended states in a two-particle plus core system is studied. The description is given in the Schrodinger picture by treating the interactions in the scattering length approximation. The treatment supports t

The ${}^{154}\mathrm{Sm}(\stackrel{\ensuremath{\rightarrow}}{d},t)$ reaction at high energy resolution $(n,\ensuremath{\gamma}),$ average resonance capture (ARC), and coincidence measurements were performed to study the deformed nucleus ${}^{153}\mat

In this paper we discuss the problem of sign ambiguity, which is common both to first and second order configuration mixing in structure calculations, as well as to the coupled channel method for scattering problems. The sign ambiguity propagates int

In inelastic scattering of 22 MeV deuterons from an isotope-separated target of $^{178}\mathrm{Hf}$ containing about 2\ifmmode\times\else\texttimes\fi{}${10}^{13}$ nuclei in the isomeric ${16}^{+}$ state we observed rotational excitation to the ${17}

The multichannel quantum defect theory is derived by using the level-matrix parametrization of the collision matrix. It is proved that the specific aspects of the multichannel quantum defect theory originate in the jump across threshold of the logari

The 22 Na( 3 He,d) 23 Mg reaction has been investigated at E τ = 30 MeV using a 22 Na implanted foil target and a Q3D spectrograph of high energy resolution. The angular distributions of deuteron groups corresponding to nineteen 23 Mg levels between
