The charge form factor of the 6Li nucleus is considered on the basis of its cluster structure. The charge density of 6Li is presented as a superposition of two terms. One of them is a folded density and the second one is a sum of the 4He and deuteron densities. Using the available experimental data for 4He and deuteron charge form factors, a satisfactory agreement of the calculations within the suggested scheme is obtained with the experimental data for the charge form factor of 6Li, including those in the region of large transferred momenta.
The even-even Selenium isotopes in the A∼80 mass region and the general features of its structure have been investigated within the framework of the interacting boson model-2. The neutron proton version of the model has been applied to the Se (A=74 to 80) isotopes with emphasis on the description of the 01+, 21+, 02+, 22+ and 41+ states. The energy levels, B(E2)and B(M1)electromagnetic transition probabilities were calculated. The results of these calculations were compared with previous experimental results and were shown to be in good agreement.
