Abstract
159Tb'un toplara nötron tesir kesitleri, 0.062 eV'dan 1 eV'a kadar olan enerji aralığında Be(1011) kristal düzlemi monokromatör olarak kullanılarak bir kristal spektrometresinde ölçülmüştür. Deney sonucunda, tek seviyeli Breit-Wigner formülüne en küçük kareler metodu uygulanarak bahis konusu enerji aralığında aşağıdaki rezonans parametreleri tayin edilmiştir;
δp = 7,96 ± 1.33 b , A = 5.50 ± 0,86 b X (eV)1/2 .
The total neutron cross section of 159Tb has been measured in the energy range from 0.062 to 1 eV with a crystal spectrometer using the Be(1011) crystal planes as a monochromator. The data in the left wing of the first neutron resonance in 159Tb were fitted directly to the one-level Breit-Wigner formula using the method of least squares. The parameters obtained from the analysis are δp = 7.96 ± 1.33 b and A = 5.50 + 0.86 b X (eV) 1/2 .
