[en] The Relativistic Mean Field (RMF) formulation is used to describe the nuclear periphery, the central theme in the study of the unstable nuclei. First, we analyze the available antiproton annihilation experimental data in terms of the extracted peripheral factors representing the ratio of neutron to proton densities at about 2.5 fm away from the half density radius of the target nucleus. Next, we calculate in the Glauber model, the reaction cross sections for A = 20 isobars as projectiles on ¹²C target using the RMF densities as input and compare with the corresponding measured cross sections. The theory (RMF) accounts well the experiment in both the cases

[en] We have demonstrated the use of secondary ion beams and stacked detector arrangement for measuring stopping power dE/dx of any stopping medium. The advantages of the present setup are that the energy and ion species can be changed with ease; moreover, data needed for determination of energy loss can be collected simultaneously. (author)

[en] Comprehensive investigations of the observed cluster radioactivity are carried out. First, the relativistic mean field (RMF) theory is employed for the calculations of the ground-state properties of relevant nuclei. The calculations reproduce the experiment well. The calculated RMF point densities are folded with the density-dependent M3Y nucleon-nucleon interaction to obtain the cluster-daughter interaction potential. This, along with the calculated and experimental Q values, is used in the WKB approximation for estimating the half-lives of the parent nuclei against cluster decay. The calculations qualitatively agree with the experiment. Sensitive dependence of the half-lives on Q values is explicitly demonstrated

[en] The production and study of the nuclei far from the stability line is of prime importance. Several current experimental and theoretical studies are devoted to the investigation and understanding of structure of these nuclei. The relativistic mean field (RMF) is able to describe successfully the observed properties of Ar isotopes

[en] Essentials of relativistic mean field (RMF) theory and some of its recent applications are presented. The explicit calculations are carried out for a few selected isotopic, isotonic, and isobaric chains of nuclei covering the entire periodic table. The calculated ground-state properties are found to be in good agreement with the corresponding experiment: the binding energies are reproduced, on the average, within 0.25%, and the charge radii differ only in the second decimal place of fermi. The relativistic origin of the pseudospin symmetry is briefly discussed. The density distributions obtained are found to be in good agreement with the experiment (where available). The peripheral factor - the ratio of the neutron and the proton densities at the nuclear periphery, extracted in the antiproton annihilation experiments - is well reproduced. The RMF densities are used to calculate the reaction (σ_R) and charge-changing (σ_cc) cross sections in the Glauber model as well as the α (cluster)-daughter interaction energy. The energy in turn is employed to estimate the decay half-lives of superheavy (transactinide) nuclei in the WKB approximation. The calculations are found to agree well with the experiment. This success of the RMF in accurately describing the nuclear properties with only a few fixed parameters is indeed remarkable

[en] The currently available Radioactive Ion Beam (RIB) facilities enable the production and the isolation of exotic nuclei produced in heavy ion reaction experiments; accelerate and then use these as secondary beams in further experimental studies. The Relativistic Mean Field (RMF) is utilised for the description of C isotopes

[en] The recent isotopic shift measurements for the chain of neon isotopes have revealed a rich structural information and very interesting anomalous behavior of the charge radii with neutron number. Here we study the systematics of the charge radii of neon isotopes within the relativistic mean field (RMF) framework. The pairing correlations are incorporated by simple constant gap approximation as well as self-consistently through the Bogoliubov transforms employing in the pairing channel the finite range Gogny-D1S or the density dependent zero range interaction. It is observed that the RMF in the axially deformed oscillator basis successfully explains the observed anomaly in the charge radii of neon isotopes

[en] The mass and the charge changing cross sections recently measured in inverse kinematics are investigated microscopically in the framework of Glauber model using the ground state point proton/neutron densities obtained in the relativistic mean field/relativistic Hartree-Bogoliubov approach. As illustrative examples, explicit results for the nuclei spanning different regions of the periodic table, incident on ¹²C, hydrogen, and -CH₂ targets are presented. The present study gives an excellent account of the experiment
