MEASUREMENTS AND EVALUATION OF NUCLEAR AND ATOMIC DATA OF THE APPLIED RADIONUCLIDES
Khlopin Radium Institute, Leningrad, USSR
XK-rays intensities of radionuclides 119mSn, 125mTe, 238Pu, 239Pu, K-shell fluorescence yield (ωK) of Mn, the intensities of γ-rays 75Se, 119mSn, 170Tm and the half-life 125mTe are measured:
ΣIXK + Iγ (119mSn) = 42.7(10) % (P=0.99; P - confidence level);
ΣIXK(125mTe) = 112.2(10) % (P=0.99);
ΣIXL(238Pu) = 10.63(32) % (P=0.99);
ΣIXL(239Pu) = 4.50(17) % (P=0.99);
ωK(Mn) = 0.340(17) (P=0.68);
Iγ(119mSn) = 15.9(3) % (P=0.68);
Iγ94(170Tm) = 2.56(7) % (P=0.95);
T1/2(125mTe) = 57.8(4) d (P=0.68).
In addition compilation, analysis and evaluation of the experimental nuclear data and atomic data, published up to 1987, were performed for 12 radionuclides put into practice (54Mn, 55Fe, 57Co, 60Co, 75Se, 109Cd, 119mSn, 125mTe, 170Tm, 238Pu, 239Pu, 241Am).
