A new technique of producing thin strip detectors was developed. The principle of the technique is the application of a low-temperature baking process instead of high temperature annealing. This thermal treatment follows the B+ ion implantation and evaporation of Al as detector contacts, which are created using a single adjusted Al mask in form of a comb. The thickness distribution along X and Y directions for a thin silicon epitaxial membrane was measured by the energy loss of α particles from 241Am ( = 5:5 MeV). Preliminary tests of the first 5 μm thin strip detector have been performed with particles and fission fragments from 252Cf. The ΔE-E ion identification plots were created using a telescope consisting of our one thin strip of the ΔE strip detector (5 μm thick) followed by a typical 300 μm Ortec E detector.

The delayed coincidence method with special reference to the in-beam experiments is considered as a means of identification and the lifetime measurements of isomeric states, as well as, the method of the investigation of radiations populating isomeric states. Isomers are detected and correlated with prompt events if they occur within a certain time of the prompt event. The 16O +208Pb reaction was investigated using the OSIRIS-II and the EAGLE arrays at HIL-UW. About eighty nuclei were identified as fission fragments among the reaction products. Several known isomeric transitions associated with reaction products in neutron-rich nuclei region were detected, as well as some new candidates were observed. [ABSTRACT FROM AUTHOR]

We present a review of barrier height distribution studies performed at the Heavy Ion Laboratory (HIL) of the Warsaw University using 20Ne beams. The barrier height distributions for the 20Ne+ 58,60,61Ni, 90,92Zr, 118Sn and 208Pb systems were experimentally determined. In some cases, a discrepancy between experimental results and the predictions of Coupled-Channels (CC) calculations was observed. We suggest that this discrepancy could be due to the cumulative effect of many individually weak channels, such as non-collective excitations of the target or transfer reactions, which cannot be implemented fully in practical CC or CRC calculations of standard form.

Preliminary results of an analysis of experiments devoted to a study of the sensitivity of the 20Ne + 208Pb quasi-elastic angular distributions at two near-barrier energies and the previously measured corresponding barrier distribution to the value of the nuclear quadrupole deformation length of 20Ne are reported.

The transfer probabilities for 20Ne + 90Zr and 20Ne + 92Zr at energies near the Coulomb barrier were measured. This quantity turned out to be very similar for both Zr isotopes and does not explain the observed differences in the barrier height distributions for these systems. [ABSTRACT FROM AUTHOR]
