Clusters in Light Nuclei

A great deal of research work has been undertaken in the alpha-clustering study since the pioneering discovery, half a century ago, of 12C+12C molecular resonances. Our knowledge of the field of the physics of nuclear molecules has increased considerably and nuclear clustering remains one of the most fruitful domains of nuclear physics, facing some of the greatest challenges and opportunities in the years ahead. In this work, the occurence of "exotic" shapes in light N=Z alpha-like nuclei is investigated. Various approaches of superdeformed and hyperdeformed bands associated with quasimolecular resonant structures are presented. Results on clustering aspects are also discussed for light neutron-rich Oxygen isotopes.Comment: 12 pages, 5 figures. Invited Talk presented by C.

Extra lightweight mechanical support structures with the integrated cooling system for a new generation of vertex detectors

The performance of new extra lightweight mechanical support structures with the integrated liquid cooling system for monolithic silicon pixel detectors has been investigated. These detectors will be used to upgrade the inner tracking system in the ALICE experiment at the CERN Large Hadron Collider. The extra lightweight mechanical support structures, together with the novel pixel detectors, provide a record-breaking total radiation length of 0.3% X 0 per layer, which will make it possible to considerably extend the physical program of investigations of the quark-gluon plasma in ultra-relativistic heavy-ion collisions at the Large Hadron Collider. This is particularly important in measuring the yields of heavy-flavor hadrons and low-mass dileptons with low transverse momenta. The experimental results of the thermal tests and the comparative analysis of five samples of extra lightweight mechanical support structures for monolithic silicon pixel detectors are presented. The high efficiency of heat drain using the liquid cooling system for a power density as high as 0.5 W/cm2 is show

Investigations of the new generation pixel detectors for ALICE experiment at LHC

We present the results from testing Monolithic Active Pixel Sensors of the detector ALPIDE (ALICE Pixel Detector). The purpose of these tests was to measure the pixel threshold and noise distributions in each of the four sectors of the detector, as well as the analysis of the hit maps produced by different radioactive sources

Experimental investigation of new ultra-lightweight support and cooling structures for the new Inner Tracking System of the ALICE Detector

Thermal cooling performances of extremely lightweight mechanical carbon fiber support structures with an integrated liquid cooling system for monolithic silicon pixel detectors have been investigated. The high heat removal efficiency using single-phase liquid flow is shown for a power density up to 0.5 W/cm$^2$. These solutions provide therefore possibility to build a detector with a record radiation length of 0.3% per layer, ensuring considerable extensions of the physical program of investigations of the quark-gluon plasma in ultra-relativistic heavy-ion collisions at the Large Hadron Collider

High-spin states in

High-spin states in 22Ne have been studied using the 14C(12C,α)22Ne(α)18O reaction at E(12 C)= 44MeV. The spin assignments were obtained as results of the analysis of double (α, α) angular correlations with the residual 18O nucleus in the 0+ ground state. The obtained values of spin and parity of five levels are: 20.0 MeV (9−), 20.7 MeV (11−), 21.6 MeV (9−), 22.2 MeV (12+), 25.0 MeV (9−)
