Ahmed}, country = {}, institution = {}, abstract = {Levenberg-Marquardt method (LM) was proposed to be applied as a non-linear least-square fitting in the analysis of a natural gamma-ray spectrum that was taken by the Hp (Ge) detector. The Gaussian function that composed of three components, main Gaussian, a step background function and tailing function in the lowenergy side, has been suggested to describe each of the y-ray lines mathematically in the spectrum. The whole spectrum has been analyzed by determining the energy and relative intensity for the strong y-ray lines.}, journal = {International Journal of Physical and Mathematical Sciences}, volume = {5}, number = {1}, year = {2011}, pages = {18 - 23}, ee = {https://publications.waset.org/pdf/3905}, url = {https://publications.waset.org/vol/49}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 49, 2011}, }
