Abstract:
The matter presented in this thesis is the author's attempt to study the properties of nuclear excited states and the radiations emitted by some radioactive nuclei by beta-gamma-gamma angular correlation method. The geometrical considerations for the mounting of the three detectors are suggested in order to make angular correlation method feasible for experimental studies of the radiations from radioactive nuclei. A few radioactive isotopes have been studied. A survey of all angular correlation data have been made and analysis of (2' ' 2') gamma-transitions in even-even nuclei are presented to get additional insight into the structure of the excited states. The thesis has been divided into the following chapters.
2112TER-I INTRODUCTION
The importance of angular correlation technique has been given. The main advantages of triple beta-gamma-gamma angular correlation over the double angular correlation are summarized......
