[en] Representative examples of experimental techniques used for the identification and study of nuclei in the close vicinity of double shell-closures are presented. Perspectives for the discovery of new doubly magic nuclei very far from stability using fragmentation or fusion-evaporation reactions including reactions with radioactive secondary beams are discussed. (author)

[en] Examples of recent results obtained with SPIRAL beams on the properties of nuclei in the vicinity of drip-lines and/or magic numbers are presented. The future plans of the GANIL/SPIRAL facility related to the SPIRAL 2 project are described. The current status of EURISOL, the european ultimate ISOL-based radioactive beam facility, is shortly presented

[en] A new version of the programme for kinematic simulation of heavy ion-induced reactions is written. This programme uses a combined standard-weighted Monte-Carlo method, and allows one to simulate both inclusive spectra and correlations between fission fragments, recoils and light particles. As a result, the angular, energy and mass distributions of reaction products in the lab. system are obtained. This programme enables one to check the theoretical model assumptions and to plan new experiments. This version of the programme is written for the PC XT/AT personal computers. 9 refs.; 2 figs

[en] The five new very neutron-rich isotopes are identified from the interaction of a 44 MeV/u ⁴⁸Ca beam with a ⁶⁴target. 5 refs.; 2 figs

[en] The analysis of elastic scattering of ⁷Li and ¹¹Li is carried out in the framework of the optical model. The experimental data for ¹¹Li are described by means of the usual optical potential. In the case of ¹¹Li the better agreement with the experiment can be obtained only using an anomalously large value of surface diffuseness of the real part of the optical potential. 15 refs

[en] The LISE code is intended to simulate medium-energy and high-energy fragment separators with electrostatic and/or magnetic selections. It is based on first-order optics and transport integral convolution techniques. Fragment separators such as LISE3, SISSI/LISE3 and SPEG at GANIL, FRS at GSI, COMBAS and ACCULINA at Dubna, A1200 and A1900 at NSCL, and RIPS at RIKEN are based on the separation of projectile-like fragments, and can be easily simulated via optical configuration files. The reaction mechanism assumed in this program is projectile fragmentation, suitable to simulate experiments at beam energies above 30 A MeV. However, built-in tools such as the physical calculator, nucleus database utilities, relativistic reaction kinematics calculations and beam optics transport calculations make it a very useful tool below this energy limit as well. The program can therefore be used for forecasting and tuning experiments using heavy-ion beams with energies ranging from 10 keV up to a few GeV per nucleon

[en] A new isomer in the neutron-rich isotope ³²Al has been identified among the fragmentation products of a ⁴⁰Ar¹⁶⁺ beam using the LISE spectrometer at GANIL. The population of the isomeric state was inferred from the detection of γ-radiation following its decay in coincidence with its respective heavy-ion implantation signal. The half-life of ^32mAl was determined to be 240 ± 30 ns. (author)

[en] Several examples of results of recent experiments performed with the SPIRAL ISOL-type and GANIL high energy radioactive beams on the properties of nuclei far from stability are presented. Future plans of the GANIL/SPIRAL facility related to the SPIRAL II project are shortly discussed. (orig.)

[en] A novel method for identification of short-lived isomers produced in heavy-ion induced reactions at several tens of MeV per nucleon and implanted at the final focus of the spectrometer is presented. Over forty known isomers have been observed at GANIL among the products of 58 and 63 AMeV ¹¹²Sn beams on a ^natNi target providing unambiguous confirmation of the ΔE-TKE-TOF based identification. Several new isomers were observed and studied in the reactions induced by ¹¹²Sn, ⁷⁸Kr, ⁴⁰Ar and ³⁶S. Future applications of the method are discussed. (orig.)

[en] The experimental status of shell structure studies in medium-heavy nuclei far off the line of β-stability is reviewed. Experimental techniques, signatures for shell closure and expectations for future investigations are discussed for the key regions around ^48,56Ni, ¹⁰⁰Sn for proton rich nuclei and the neutron-rich N=20 isotones, Ca, Ni and Sn isotopes
