title: Study of the continuous internal bremsstrahlung spectrum from (204)Tl by using singular value decomposition.
abstract: Internal bremsstrahlung (IB) accompanying the β(-) decay of (204)Tl was measured using a 5.08×5.08cm(2) NaI(Tl) detector employing a magnetic deflection method in the range of 10-760keV. A novel approach, the Singular Value Decomposition (SVD), is applied to unfold the raw detector spectrum of (204)Tl. Unfolded IB spectrum is compared with the KUB theory. The measured spectrum is found to show fairly good agreement with the KUB theory in the energy range of 100-600keV. The distribution beyond the 600keV takes a positive deviation from the theory.
