Least square methods and covariance matrix applied to the relative efficiency calibration of a Ge(Li) detector
Description
The methodology of covariance matrix and square methods have been applied in the relative efficiency calibration for a Ge(Li) detector apllied in the relative efficiency calibration for a Ge(Li) detector. Procedures employed to generate, manipulate and test covariance matrices which serve to properly represent uncertainties of experimental data are discussed. Calibration data fitting using least square methods has been performed for a particular experimental data set. (author)

A metodologia de matriz de covariancia e metodos de minimos quadrados foram aplicados na calibracao de eficiencia relativa para um detector de Ge(Li). Os procedimentos empregados para gerar, manipular e testar matrizes de covariancias, que servem para representar apropriadamente incertezas de dados experimentais, sao discutidos. O ajuste dos dados de calibracao foi efetuado, para um particular conjunto de resultados experimentais, utilizando metodos de minimos quadrados. (autor)Files
