In this paper, we report on a relatively new scintillator - LaBr3:Ce for gamma-ray spectroscopy. Crystals of this scintillator have been grown using Bridgman process. This material when doped with cerium has high light output ( 60000 photons/MeV) and fast principal decay constant (≤ 25 ns)...

As for the Moon, X-ray spectroscopy of resonantly scattered solar X-rays can be used to map the elemental composition of the surface. NEAR-Shoemaker entered an Eros orbit on February 14, 2000, and completed a 1-year-long mission around it. Eros at 33 × 13 × 13 km in size is the...

In this work, we report on the effects observed in MAPbI(3) polycrystalline films and solar cells under moderate gamma-ray doses of 3-21 kGy. We applied several instrumental techniques such as photoluminescence spectroscopy, time-resolved photoluminescence, Suns-VOC measurement, and impedance spectro...

Gamma-ray bursts (GRBs) are flashes of high-energy radiation arising from energetic cosmic explosions. Bursts of long (greater than two seconds) duration are produced by the core-collapse of massive stars1, and those of short (less than two seconds) dura

, 1977). The material under consideration should also have a relatively high average atomic number if used in gamma ray spectroscopy to increase the gamma ray interaction probability. High charge carrier mobilities and long charge carrier lifetimes are also needed to ensure efficient charge carrier ...
