Transmission resonance spectroscopy in the third minimum of 232Pa
L. Csige, M. Csatlos, T. Faestermann +8
The fission probability of 232Pa was measured as a function of the excitation energy in order to search for hyperdeformed (HD) transmission resonances using the (d,pf) transfer rea…
Neutron-skin thickness of Pb, and symmetry-energy constraints from the study of the anti-analog giant dipole resonance
A. Krasznahorkay, M. Csatlós, L. Csige +12
The Pb(,) Pb reaction at a beam energy of 30 MeV has been used to excite the anti-analog of the giant dipole resonance (AGDR) and to measure its -…
New evidence supporting the existence of the hypothetic X17 particle
A. J. Krasznahorkay, M. Csatlos, L. Csige +8
We observed electron-positron pairs from the electro-magnetically forbidden M0 transition depopulating the 21.01 MeV 0 state in He. A peak was observed in their an…
A pair spectrometer for measuring multipolarities of energetic nuclear transitions
J. Gulyás, T. J. Ketel, A. J. Krasznahorkay +7
A multi-detector array has been designed and constructed for the simultaneous measurement of energy- and angular correlations of electron-positron pairs. Experimental results are o…
Observation of the X17 anomaly in the decay of the Giant Dipole Resonance of Be
A. J. Krasznahorkay, A. Krasznahorkay, M. Csatlós +6
Angular correlation spectra of pairs produced in the Li(,)Be nuclear reaction were studied at a proton beam energy of ~=~4.0~MeV, which corresponds…
New anomaly observed in C supports the existence and the vector character of the hypothetical X17 boson
A. J. Krasznahorkay, A. Krasznahorkay, M. Begala +8
Employing the B(p,)C nuclear reaction, the angular correlation of pairs was investigated in the angular range of for five diff…
