F. Cusanno, S. Širca et al. High-Resolution Spectroscopy of ?16N by Electroproduction

An experimental study of the 16O(e,e'K+)?16N reaction has been performed at Jefferson Lab. A ground-state binding energy of 13.76±0.16??MeV was obtained for ?16N with better precision than previous measurements on the mirror hypernucleus ?16O. Precise energies have been determined for peaks arising from a ? in s and p orbits coupled to the p1/2 and p3/2 hole states of the 15N core nucleus.

M. Vencelj, R. Novak Gauss-Seidel iterative method as a real-time pile-up solver of scintillation pulses.

We study here a real-time capability of the event-by-event correction method, which at the core translates to solving many sets of linear equations. We propose a novel approach based on the Gauss-Seidel iterative method, which turns out to be a stable and cost-efficient solution to improve spectroscopic resolution in the front-end electronics.

B. Golli, S. Širca, M. Fiolhais Pion electro-production in the Roper region in chiral quark models

We present a method to calculate pion electro-production amplitudes in a coupled-channel framework incorporating quasi-bound quark-model states. The method offers a clear prescription how to extract the resonant part of the amplitudes, even in the presence of different decay channels and a strong mixing of neighbouring resonances.

P. Achenbach, L. Debenjak, S. Širca et al. Front-End Electronics for the KAOS Spectrometer at MAMI

A new front-end electronics system has been developed for the electron arm tracking detectors in the Kaos spectrometer at the Mainz microtron MAMI.

M. Vencelj, K. Bučar, R. Novak, H.J. Wörtche Event by event pile-up compensation in digital timestamped calorimetry

In digital nuclear calorimetry, the effect on measured pulse amplitudes by piling up of pulses can be compensated based on the pulses’ respective timestamps. We propose here a compensation method, suitable for real-time as well as off-line implementation.
