چکیده
In this study, the gamma and X-ray emission intensities of 161Tb were determined using a high-purity germanium spectrometer. The samples used previously standardised by coincidence counting Triple to Double Coincidence Ratio (TDCR) methods. A total 28 gamma-rays 4 X-rays measured compared with previous measurements performed more than 30 years ago. Most lines are in agreement, while large discrepancies observed for 5 lines. uncertainties have been dramatically decreased respect giving better knowledge 161 Tb day.

Determination of X- and gamma-ray emission intensities in the decay of (131)I.
The activity per unit mass of an iodine-131 solution was absolutely standardized by both the 4πβ-γ coincidence method and the 4πγ counting technique. The calibrated solution was used to prepare point sources after a preliminary deposit of AgNO3 to prevent the loss of volatile iodine. Relative and absolute photon emission intensities of 15 sgamma-rays and those of the two K X-rays of xenon were ...
متن کاملX-Ray Emission of Gamma-Ray Bursts
X-ray emission can provide a crucial diagnostic of gamma-ray bursts (GRBs). We calculate the X-ray and gamma-ray spectra of impulsive acceleration episodes related to GRB pulses. We use the synchrotron shock model (SSM) as a basis of our calculations. We show that the current data on soft-to-hard emission ratios of GRB pulse emission are in agreement with the SSM. In particular, GRB pulse emiss...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولX–ray Emission in Gamma-ray Blazars
As shown by Maraschi (this volume) the overall spectral energy distribution (SED) of the blazars detected by EGRET shows two peaks, in a ν–νF (ν) plot. With few exceptions, the minimum between these two peaks occurs in the X–ray range. We can exploit this observational fact to constrain the models proposed to account for the SED of blazars, and to reach an important conclusion: the conversion o...
