Estimation based on probability-weighted moments is a well-established method and an excellent alternative to the classic of or maximum likelihood method, especially for small sample sizes. In this research, we developed new class estimators parameters Pareto type I distribution. A generalization approach foundation estimators. It has advantage being valid in entire parameter space We establish...

A recently proposed scaling law for the decay time of alpha particles is generalized for cluster decay. It is shown that for the decay of even-even parents, logT1/2 depends linearly on the scaling variable S=(ZcZd) 0.6/ √ Qc and on the square root of the reduced mass of cluster and daughter.
