Code number: 62 44 05 01 Thesis Submitted for the Doctoral Degree of Science Thesis Supervisors 1. Ass.Prof. Le Hong Khiem 2. Ass.Prof. Vuong Huu Tan Hanoi - 2013Statement of authorship I hereby certify that the present dissertation is my own research work under guidance of my supervisors. All the data and results presented in this dissertation are true and correct. They are based on the results and conclusions of eleven papers written in co- authorship with my collaborators. All of them have been published in peer-review journals and science reports. These results have also been reported at European Nuclear Physics Conference 2012 and seminars in Romania, Japan and Vietnam. This approbation process guarantees that these results have never been published by anyone else in any other works or articles. Some results from other studies used to compare and discuss with our new data are noted clearly as references. Nguyen Ngoc Duy i-1Acknowledgements First, I would like to thank my supervisors in Vietnam, Ass.Prof. Le HongKhiem and Ass.Prof. Vuong Huu Tan. They are my good supervisors since theyare always able to give me kind suggestions and talk with me like a friend. Asthe supervisors, they are very kind to give me scientific knowledge. They giveme a chance to go abroad to study at many classes and attend many wonderfulconferences. They teach and direct me carefully to complete this thesis. Second, I would like to give my deeply thank to my supervisor in Japan,Prof. Dr. Shigeru Kubono at the University of Tokyo. He is not only a famousscientist but also a very kind supervisor. He always very nicely gives me clearand patient guidance that helps me to conduct my research. He supports me inscience as well as finance to study and perform the experiment of this workduring I stay in Japan. I also owe my thanks to Dr. Pham Dinh Khang, Ass.Prof. Nguyen NhiDien and Dr. Phu Chi Hoa who give me many meaningful advices and help meto finish the PhD course. Thanks to their kind encouragement and organizationfor the thesis committee. It would be inappropriate not to mention Dr. Nguyen Xuan Hai, Dr. DamNguyen Binh and Mr. Nguyen Duy Ly for their kind discussion. I mustemphasize their readiness to share their knowledge and experience. I would also like to thank all of our collaborators at the CRIB facility fortheir help to perform my experiment successfully. I especially thank Dr.Hidetoshi Yamaguchi and David Miles Kahl at CNS who helped me with theirbest efforts during the beam time. Last but not least, I thank my family and my friends for supporting me allthe time. This thesis is as a present sent to my lovely departed father. Althoughhe was very sore because of cancer, during his hospital time, he encouraged mea lot. i-2 Symbols and abbreviationList of Symbols and AbbreviationsADC : Analoge – Digital Converter.CAMAC : Computer Automated Measurement and Control.cm : centimeter.enA : electron-nanoAmpere.eµA : electron-microAmpere.FADC : Flash ADC.Fm : Fermi (10-15 m).g : gram.GK : Giga Kelvin (109 K)GSI : The GSI Helmholtz Centre for Heavy Ion Research.GEM : Gas-Electron Multiplier.HDD : Hard disk.JINA : Joint Institute for Nuclear Astrophysics-Michigan State UniversityK : temperature scale Kelvin.k : Boltzman constant.keV : kilo-electron-Volt.kHz : kilo Hertz.kV : kilo-Volt.MΘ : Solar mass.MeV : Mega-electronVolt.MeV/u : ...
