Abstract

Abstract: Pairing is collective phenomenon caused by fermions as neutron and proton collected in nuclei, this phenomenon can be found in the formation of isotopes such as the Cr-isotopes. Pairing has an impact on the amount of nuclear binding energy. Like as social being uniquely, fermions will have a strong relationship when collected in nuclei isotopes. Their binding energy will increase when the nuclei have a paired of even-even number neutron or proton. One of the most powerful approaches in explaining the pairing effect is the Bardeen-Cooper-Srhrieffer approximation (BCS-Approximation), which is forms the basis of the theory superfluidity phenomenon in nucleiIn BCS-Approximation requires an interaction potential matrix that describes the neutron interactions between energy levels. We used uniform fixed potential energy 0.5 MeV, 0.1 MeV, and 0.01 MeV which is will be an option in this approach to calculate the total binding energy in Cr-isotopes.Abstrak: Pairing merupakan fenomena keloktif dari beberapa fermion yang berkumpul, fenomena ini dapat ditemukan pada pembentukan isotop seperti isotop Cr. Pairing atau pasangan akan berdampak pada besar energi ikat inti atom, seperti halnya makhluk sosial yang akan meemliki hubungan yang kuat ketika berkumpul, isotop suatu nuklida juga akan mengalami peningkatan energi ikat ketika jumlah partikel semakin banyak dan berjumlah genap atau berpasangan. Salah satu pendekatan yang sangat powerfull dalam menjelaskan pairing effect tersebut adalah pedekatan Bardeen, Cooper, dan Schrieffer yang dikenal dengan BCS Approximation, yang menjadi dasar teori dari fenomena superfluidity. Penggunaan pendekatan ini memerlukan matriks potensial interaksi yang menggambarkan interaksi neutron antar level energi, penggunaan Uniform Fixed Potential Interaction yang bernilai 0.5 MeV, 0.1 MeV, dan 0.01 MeV menjadi salah satu pilihan dalam pendekatan ini untuk menghitung energi ikat total inti isotop Cr.

Abstract

The charge-radii nuclei is distribution of the coulomb effect but respectively isn’t distribution of proton due to affected by the scattering of electrons in nuclei and is an observable quantity in laboratory. In this research, we use RMF model in Ca-isotopes with and without electromagnetic exchange form, and be compared with experiment from IAEA. With a fairly good accuracy (above 99%) on the binding energy, it shows that this model is powerful. Unfortunately, at the correlation to charge-radius, even with good enough accuracy (above 97%), it still doesn't show electromagnetic exchange corellation. An analysis of all RMF forms is needed to get a better correlation to the charge-radii nuclei clearly here.
