Statistically significant observation of and cross sections for a new nuclear reaction channel on 197Au with bound dineutron escape

Autor: Kadenko, I. M., Biro, B., Fenyvesi, A.

A new nuclear reaction channel on 197Au with the neutron as a projectile and a bound dineutron (^2n) in the output channel is considered based on available experimental observations. The dineutron is assumed to be formed as a particle-satellite, sepa

A Comparison of the Effects of Neutron and Gamma Radiation in Silicon Photomultipliers

Autor: Biró, B., David, G., Fenyvesi, A., Haggerty, J. S., Kierstead, J., Mannel, E. J., Majoros, T., Molnar, J., Nagy, F., Stoll, S., Ujvari, B., Woody, C. L.

The effects of radiation damage in silicon photomultipliers (SiPMs) from gamma rays have been measured and compared with the damage produced by neutrons. Several types of MPPCs from Hamamatsu were exposed to gamma rays and neutrons at the Solid State
