Experimental Nuclear Physics is the practical investigation of the processes that occur at the heart of an atom. The majority of information from the nucleus is obtained by studying the radiation emitted by radioactive nuclei or by nuclear reaction products, and therefore, one of the fundamental techniques in nuclear research is the detection of radiation detector. With this aim, a wide range of detectors has been developed, each one with very special characteristics in accordance with the use and application for which it has been designed.The first chapter briefly describes the various types of nuclear radiations and their sources, and is followed by the study of different types of radiation detectors that were used in this work. In the second chapter, the energy resolution for α-particles from Am-Pu source has been studied using the Silicon semiconductor detector, and we have also done the alpha particle transmission experiment. In the third chapter, particle identification has been studied using the zero crossover technique of pulse shape discrimination and Ballistic deficit. In the fourth chapter, we have investigated proton energy from 27Al (α, p)30Si reaction using Energy loss measurement technique.

Keywords: Energy struggling, Zero crossover method, Pulse shape discrimination, Particle identification.
