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…
Bombardment of CO ice by cosmic rays: I. Experimental insights into the microphysics of molecule destruction and sputtering
Alexei V. Ivlev, Barbara M. Giuliano, Zoltán Juhász +12
We present a dedicated experimental study of microscopic mechanisms controlling radiolysis and sputtering of astrophysical ices due to their bombardment by cosmic ray ions. Such io…
Proton and electron irradiations of CH4:H2O mixed ices
Duncan V. Mifsud, Péter Herczku, Béla Sulik +7
The organic chemistry occurring in interstellar environments may lead to the production of complex molecules that are relevant to the emergence of life. Therefore, in order to unde…
Sulfur Ion Implantations Into Condensed CO2: Implications for Europa
D. V. Mifsud, Z. Kaňuchová, P. Herczku +12
The ubiquity of sulfur ions within the Jovian magnetosphere has led to suggestions that the implantation of these ions into the surface of Europa may lead to the formation of SO2.…
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 differ…
Observation of the X17 anomaly in the Li(,)Be direct proton-capture reaction
N. J. Sas, A. J. Krasznahorkay, M. Csatlós +8
Angular correlation spectra of pairs produced in the Li(,)Be nuclear reaction have been studied at the sharp = 441 keV resonance as well as at …
The Ice Chamber for Astrophysics-Astrochemistry (ICA): A New Experimental Facility for Ion Impact Studies of Astrophysical Ice Analogues
Péter Herczku, Duncan V. Mifsud, Sergio Ioppolo +11
The Ice Chamber for Astrophysics-Astrochemistry (ICA) is a new laboratory end-station located at the Institute for Nuclear Research (Atomki) in Debrecen, Hungary. The ICA has been…
Spatial and temporal distribution of a 1-MeV proton microbeam guided through a poly(tetrafluoroethylene) macrocapillary
G. U. L. Nagy, Z. T. Gaál, I. Rajta +1
We present computer simulations about the spatial and temporal evolution of a 1-MeV proton microbeam transmitted through an insulating macrocapillary with the length of 45 mm and w…
Cross section measurement of the astrophysically important 17O(p,gamma)18F reaction in a wide energy range
Gy. Gyürky, A. Ornelas, Zs. Fülöp +7
The 17O(p,g)18F reaction plays an important role in hydrogen burning processes in different stages of stellar evolution. The rate of this reaction must therefore be known with high…
Experimental Setup for Studying Guiding of Proton Microbeam
G. U. L. Nagy, I. Rajta, R. J. Bereczky +1
We present the design and construction of our experimental setup for studying the transmission of proton microbeam through a single, cylindrical shape, macroscopic insulating capil…
