Medium-mass neutron-rich nuclei are important for nuclear structure investigations (e.g. shell evolution with neutron excess) and nuclear astrophysics (e.g. r-process in nucleosynthesis). However, these investigations are limited because of the difficulties in producing medium-mass nuclei with a large neutron excess. The traditional way for producing neutron rich nuclei was fission of actinides...
In this study, a mixture of waste lead mine Nakhlak and cement with different percentages of boric acid are used to construct a proper shield for gamma and neutron radiations emitted from the Am-Be source. Neutron dose rate reduction by the prepared samples was investigated by thermal neutron irradiation system of Isfahan University, TLD 600 and TLD 700. Neutron dose rate changes, compressive...
