“…with the 13N (g.s.) wave-function appears as a factor in Equation (4) and has been set to Y= 0.53, according to [12]. The normalization N can be taken from a Woods-Saxon potential wave-function calculated in a p + a2C potential obtained from an analysis [13] of elastic electron scattering by z3C.…”

Absolute differential cross-sections of p+ a2C elastic scattering have been measured at 0cm=89.1 ~ 118.7 ~ 146.9 ~ for bombarding energies between 0.3 and 2.0MeV. Revised level parameters of the first three excited states in ~3N have been extracted with a R-matrix analysis. It is shown that the influence of the bound ground-state of ~ 3N has an appreciable effect on low-energy scattering. Recent predictions concerning Mott-Schwinger polarization are also discussed.

We present an exploratory study of structure of 13 C, 15 C, 17 C and 19 C, showing that the simple one-quasiparticle projected BCS (PBCS) model is capable to account for several important properties of these nuclei. Next we discuss the importance of the Pauli Principle in the particle-core models of normal-parity states in 13 C and 11 Be. This is done by considering the pairing interaction between nucleons moving in an over-all deformed potential. To assess the importance of pairing correlations in these light nuclei we use both the simple BCS and the PBCS approximations. We show that the Pauli Principle plays a crucial role in the parity inversion in 11 Be. It is also found that the effect of the particle number conservation in relatively light and/or exotic nuclei is quite significant. Comparison of our results with several recent papers on the same subject, as well as with some experimental data, is presented.

“…This means that the particle-GDR coupling is to be cut-off at the r = R C. This basic idea is essentially same as the one of J. Zim~myi et al [-4] on the effective charge factor for the radiative capture of the fast nucleons. In the preceding schematic limit, this approximation gives <J fl rO(r-Rc) [Ji> eeff = eel (9) (jr[ r [Jl) or, in the form of r-dependent effective charge, These results give us the following physical picture: Only outside from the Rc, the single particle transition occurs freely with the effective charge eel f =eel. On the other hand, inside of the nucleus, the transition is completely hindered since the GDR of the core is virtually excited.…”

“…The effective boundary is the cutoff radius, R c, which is to be chosen as about nuclear force range plus the core radius. As (9) and (10) tell us, it is essential to adopt the radial wave functions with correct asymptotic behavior, as actually done in the Sect. 3 and 4.…”

Although El-transition between levels below giant dipole resonance are almost always strongly hindered, there are several exceptions as observed in i~Be and ~3C. These fast El-transitions are studied by adopting a simple "cutoff" model, in which the behavior of single particle wave functions only outside of the nucleus contribute. The results are compared with the particle-GDR coupling model. The reason why the El-hindrance disappears is explained. We also investigate the direct capture of thermal neutron by 4~and N= 82 nuclei, where similar situation is observed. Further, the implication of the direct capture in multiple neutron capture is discussed.
