— We present the first optical observations of a Gamma Ray Burst (GRB) afterglow using the 2-m robotic Liverpool Telescope (LT), which is owned and operated by Liverpool John Moores University and situated on La Palma. We briefly discuss the capabilities of LT and its suitability for rapid follow-up observations of early optical and infrared GRB light curves. In particular, the combination of a...

The current gamma-ray/neutron instrumentation development effort at NASA Goddard Space Flight Center aims to extend the use of active pulsed neutron interrogation techniques to probe the subsurface elemental composition of planetary bodies in situ. Previous NASA planetary science missions, that used neutron and/or gamma-ray spectroscopy instruments, have relied on neutrons produced from galacti...

Crystal growth and detector fabrication technologies have reached such a state of maturity that high-quality large-volume CeBr3 scintillators can now be produced with dimensions of 2′′×2′′ and well above. We present a study of CeBr3 samples of various dimensions and show that they have a number of advantages over equivalently sized LaBr3:5%Ce for gamma-ray spectroscopy applications requiring hi...

Proximal gamma-ray spectroscopy is a consolidated technology for continuous and real?time tracing of soil water content at field scale. New developments have shown that this method can also act as an unbiased tool remotely distinguishing rainwater from irrigation without any meteorological support information. Given single detector, the simultaneous observation in gamma spectrum transient incre...

A high resolution Compton telescope has been identified by the Gamma Ray Astronomy Program Working Group (GRAPWG) as the highest priority major mission in gamma ray astrophysics following GLAST. This mission should provide 25-100 times improved sensitivity, relative to CGRO and INTEGRAL, for MeV gamma ray lines. It must have good performance for narrow and broad lines and for discrete and diffu...

Since its launch in October 2002, ESA’s INTEGRAL observatory has enabled significant advances to be made in the study of Galactic nucleosynthesis. In particular, the imaging Ge spectrometer SPI combines for the first time the diagnostic powers of high resolution gamma-ray line spectroscopy and moderate spatial resolution. This review summarizes the major nucleosynthesis results obtained with IN...

To understand the mechanism of charge symmetry breaking between 4 Λ H and He, we plan to measure gamma-transition energy (1 + → 0 ) with a Ge detector array. For identification hypernucleus, will perform triple coincidence reaction, γ -ray, weak decay for first time. We pion from range counter. This method enable -ray spectroscopy various hyperfragments which cannot be directly produced by ( K ...
