Gamma-Ray Energies and Relative Intensities of ⁷⁵Se, ^108mAg, ¹¹³Sn, ¹³¹I and ¹³³Ba

Abstract

Gamma-ray energies lower than 500 keV and relative intensities have been precisely measured with Ge(Li) detectors. Many experimental effects such as the source position effect, the counting rate effect, the room temperature effect, etc. are examined. Results are as follows: 303.916±0.012 and 400.624±0.030 keV for 75 Se; 433.932±0.014 keV for 108 m Ag; 255.126±0.010 (3.33±0.13) and 391.686±0.027 keV (100) for 113 Sn; 364.456±0.031 keV for 131 I; 161 (0.98±0.07), 223 (0.76±0.05), 276 (11.6±0.5), 302.839±0.008 (29.6±1.1), 355.999±0.024 (100) and 383.841±0.027 keV (14.9±0.6) for 133 Ba. Parentheses show relative intensities.
