Determination of the Activation Energy of a TL Peak Without Prior Knowledge of Order of KineticsBy I. Bhattacharyya, B. Romesh Sharma, S. K. Azharuddin, S. D. Singh, P. S. Majumdar
Abstract: In the present study, we extend the peak shape method of Chen for fractional intensities x =2 3 and 4 5.The novelity of the method is that it does not require the prior knowledge of order of kinetics which does not admit a straight forward evaluation. The present method has been successfully applied to computer generated TL peaks resulting from kinetic order model (KOM). The validity of the present sets …

On an alternative concept of the symmetry factor based on skewness of a TL peakBy Sk. Azharuddin, Bikash Kumar Sarkar, Indranil Bhattacharyya, Ananda Sarkar, P. S. Majumdar, S. Dorendrajit Singh
Abstract: Symmetry factor is very crucial in the analysis of Thermoluminescence (TL) peaks. Knowledge of symmetry factor is required for the evalution of trapping parameters of a TL peak. The usual symmetry is denoted by shape factor of the peak. In the present paper an alternative concept of symmetry factor of the TL peak based on its skewness is developed. The present findings are applied both to computer generated and experimental …
