Single-particle resonances in deformed nuclei are considered using the coupled-channel Schrödinger equation method with the outgoing boundary conditions. Two variants of this method are investigated: the non-adiabatic one (based on the weak-coupling scheme) and the adiabatic one (based on the strong coupling). The R-matrix theory and the Gamow state approach are discussed and compared with each other. It is shown that the widths of very narrow proton resonances can be calculated by combining the harmonic oscillator expansion method with the R-matrix approach

In order to progress towards a stored polarized antiproton beam, it is crucial to understand the interaction of polarized protons with unpolarized electrons. Therefore investigations that address in particular the...

    A dual partial snake scheme has been used for AGS polarized proton operation for several years. It has provided polarized proton beams with 1.5×1011 protons per bunch and 65% polarization for the RHIC spin program. There is still residual polarization loss due to both snake resonances and...
