“…The gamma radiation in this region is very much more intense than in the anticenter region, in agreement with the observations made with the OSO-III experiment of Kraushaar et al (1973), and exhibits a narrow distribution (The 2a width is no more than 60.) along the plane which is nearly uniform in intensity from 3300 to 300.…”

“…Kraushaar et al (1973) with a gamma ray experiment flown on OSO-III saw an enhanced radiation coming from the galactic plane whose angular width was less than their detector angular resolution (-350 full width half maximum intensity). The radiation away from the galactic center region was observed to have a line intensity consistent with that expected from cosmic rays interacting with matter in the galactic plane (e.g.…”

“…Ginzburg & Syrovatskii (1964) summarized the elementary process for gamma-ray production and discussed diffusion and propagation of cosmic rays in the Galactic disk. As a result, it is quite natural to expect gamma rays from the Galactic plane; however, it was 20 years after the pioneering work by Feenberg & Primakoff (1948) until the intense band of gamma-ray intensity along the Galactic plane was observed with OSO 3 (Kraushaar et al 1972) and a balloon-borne detector (Fichtel et al 1972). Advanced observations were carried out by detectors borne on SAS 2 (Fichtel et al 1975;Hartman et al 1979) and COS B (Mayer- Hasselwander et al 1980Hasselwander et al , 1982.…”

Data from the Tibet III air shower array (with energies around 3 TeV) and from the Tibet II array (with energies around 10 TeV) have been searched for diffuse gamma rays from the Galactic plane. These arrays have an angular resolution of about 0=9. The sky regions searched are the inner Galaxy, 20 l 55 , and outer Galaxy, 140 l 225 , and jbj 2 or 5 . No significant Galactic-plane gamma-ray excess was observed. The 99% confidence level upper limits for gamma-ray intensity obtained are (for jbj 2 ) 1:1 Â 10 À15 cm À2 s À1 sr À1 MeV À1 at 3 TeV and 4:1 Â 10 À17 cm À2 s À1 sr À1 MeV À1 at 10 TeV for the inner Galaxy, and 3:6 Â 10 À16 cm À2 s À1 sr À1 MeV À1 at 3 TeV and 1:3 Â 10 À17 cm À2 s À1 sr À1 MeV À1 at 10 TeV for the outer Galaxy, assuming a differential spectral index of 2.4. The upper limits are significant in the multi-TeV region when compared to those from Cerenkov telescopes in the lower energy region and other air shower arrays in the higher energy region; however, the results are not sufficient to rule out the inverse Compton model with a source electron spectral index of 2.0.

Abstract. The Earth's high energy gamma-ray emission is caused by cosmic ray interactions with the atmosphere. The EGRET detector on-board the CGRO satellite is only the second experiment (after SAS-2) to provide a suitable dataset for the comprehensive study of this emission. Approximately 60% of the EGRET dataset consist of gamma photons from the Earth. This conference contribution presents the first results from the first analysis project to tackle this large dataset. Ultimate purpose is to develop an analytical model of the Earth's emission for use in the GLAST project. The results obtained so far confirm the earlier results from SAS-2 and extend them in terms of statistical precision and angular resolution.
