Attendance: All university employees, and we recall the invitation of all students of the department, especially students of graduation projects.
This seminar comes within a series of bi-monthly seminars organized by the Scientific Seminars Committee of the Department of Physics and presented by faculty members of the Department and researchers from other research bodies, and this series of seminars is supervised by the coordinator of the Department Mr. Mervat Al-Zumea, and coordinated and managed by the Scientific Seminars Committee.
These seminars aim to stimulate the climate of scientific research in the department and inform its employees of the latest developments in the physical sciences in various fields.
It is worth mentioning that attendance at these seminars is available to all university employees, including faculty members, employees and students.

With the greetings of the Scientific Committee of the Department of Physics.
Abstract:
In this research polonium isotopes with mass numbers A = 195 - 199 were studied, with a particular focus on 195Po and .197Po these isotopes were produced in ISOLDE/CERN and accelerated to the ISOLTRAP experiment to perform mass measurements and spectroscopy. Spectroscopy studies of alpha particles were first conducted in ISOLTRAP with the help of the time mass spectrometer of multiple reflections. (MR-TOF MS) then the mass Po(195,197) was accurately measured with the Penning-trap mass spectrometer, through which the energy of the raised 13/2+ level was determined and arranged in the cortex model for the first time. Furthermore, the energy of the 13/2+ excited level was determined and arranged in lead, radon and radium by alpha decay chains.
Abstract
The measurements that will be presented investigate the neutron-deficient polo- nium isotopes in the region of A = 195 − 199, with a special emphasis on 195Po and 197Po. These isotopes were produced at ISOLDE/CERN and delivered to the ISOLTRAP experiment where mass measurements and α-decay spectroscopy were performed. The decay-spectroscopy studies were carried out for the first time at ISOLTRAP with the support of the multi-reflection time-of-flight mass spectrometer (MR-TOF MS). The masses of (195,197)g,mPo were measured pre- cisely with Penning-trap mass spectrometry, from which the state ordering and the energy of the 13/2+ states in 195,197Po were determined for the first time. Furthermore, the state ordering and the energy of the 13/2+ state in lead, radon, and radium were obtained through α-decay chains. The new data complete the knowledge of the energy systematics in this region. The presented mass mea- surements provide information on the behaviour of the 13/2+ states in the lead region near N = 104, which remain excited states.

As part of the plan of deanship of talent, creativity and excellence and its interest in building a knowledge society and achieving sustainable development through the care of talented and creative people, the deanship organized a scientific trip to king Abdullah city of atomic and renewable energy (mashka) and was prepared for the trip dr. Samah al Hakami as an agent deanship of talent, creativity and excellence and the owner of the students in the journey professor serry al-Madalj from the levels of deanship where the target group in the trip was students of the preparatory year with three supervisors in order to introduce them to modern innovations and various jobs in the field of energy and to help them with interactive experiences, interactive programs and presentations through which energy technologies are crystallized from the past era to the present, in addition to the discovery of new and up-to-date information about energy, and the exit of the students under the supervision of dr. Samah al-hakami indicated to them that they represent imam Mohammed bin Saud Islamic university explaining the instructions to them.
Renewable Energy investment center
https://units.imamu.edu.sa/administrations/ithmar/announcements/Pages/administrations001.aspx
Definition:
The center is working on projects that provide alternative sources of energy, allowing for the optimal exploitation of the natural resources available in the country, and relies on modern technologies and clean and environmentally friendly energy such as projects that rely on clean nuclear energy or rely on nanotechnology. this energy is then used for civilian purposes that facilitate the nature of civilian life and reduce economic costs for individuals and the government alike, which reflects positively on the level of social welfare in the country.It is no secret that the solar energy project has promising advantages, both in the near term and in the long run, and investing in it through alliance with specialized international companies achieves a solid progress in this vital field, at the local, gulf and Arab level as well. Saudi Arabia seeks to be a leader in this field, through its large project, king Abdullah city of atomic and renewable energy
Vision:
The center should be active in building an investment technical partnership between the center and the innovative private sector or investors, in addition to experts to achieve the fund "ithmaar" self-resource sufficiency, which supports the performance of the university's mission.
The message.
The center establishes specialized initiatives in the field of renewable energy, and provides specialized scientific, technical and professional studies and consultations, with high efficiency and quality in accordance with international standards and methods.
