Spallation-altered accreted compositions for X-ray bursts: Impact on ignition conditions and burst ashes
J. S. Randhawa, Z. Meisel, S. A. Giuliani +5
Dependable predictions of the X-ray burst ashes and light curves require a stringent constraint on the composition of the accreted material as an input parameter. Lower metallicity…
Development of the TIP-HOLE gas avalanche structure for nuclear physics/astrophysics applications with radioactive isotope beams: preliminary results
Jaspreet Singh Randhawa, Marco Cortesi, Wolfgang Mittig +2
We discuss the operational principle and performance of new micro-pattern gaseous detectors based on the multi-layer Thick Gaseous Electron Multiplier (M-THGEM) concept coupled to…
Beam induced space-charge effects in Time Projection Chambers in low-energy nuclear physics experiments
J. S. Randhawa, M. Cortesi, Y. Ayyad +14
Tracking capabilities in Time Projection Chambers (TPCs) are strongly dictated by the homogeneity of the drift field. Ion back-flow in various gas detectors, mainly induced by the…
Direct observation of proton emission in 11Be
Y. Ayyad, B. Olaizola, W. Mittig +30
The elusive decay was observed in Be by directly measuring the emitted protons and their energy distribution for the first time with the prototype Active Tar…
Nuclear spallation in active galaxies
L. C. Gallo, J. S. Randhawa, S. G. H. Waddell +3
A number of works point to the presence of narrow emission features at unusual energies in the X-ray spectra of active galactic nuclei (AGN) or to potentially low iron abundances a…
Observation of excited states in Mg sheds light on nuclear forces and shell evolution
J. S. Randhawa, R. Kanungo, M. Holl +35
The exotic Borromean nucleus Mg with = 8, located at the proton drip-line provides a unique testing ground for nuclear forces and the evolution of shell structure in the…
