The cross section for the pp → pn π + reaction has been measured at 492 MeV by using the large acceptance ANKE magnetic spectrometer placed at an internal target position of the storage ring COSY-Jülich. The produced proton and pion were detected in coincidence in a region close to the forward direction such that the excitation energy in the np system was below 3 MeV. This is the region of the ...

We review some salient aspects of calculations of the neutrino-nucleus reaction cross sections in the low energy range (1-100 MeV).

The analyzing power of pp → ppπ 0 reaction has been measured at the beam energy of 390 MeV. The missing mass technique of final protons has been applied to identify the π 0 production event. The dependences of the analyzing power on the pion emission-angle and the relative momentum of the protons have been obtained. The angular dependence could be decomposed by the Legendre polynomial and the r...

The neutron–9Li interaction and the corresponding low-energy 10Li spectrum are decisive for the properties of 11Li described as a three-body system (n+n+9Li). We compute structure and breakup properties of 11Li as function of this interaction. The hyperfine structure due to the spin 3/2 of both 9Li and 11Li is needed and treated with special care. We use the hyperspherical adiabatic expansion o...
