O164800100025 (O,D0160001,O.R.Kakuee+,J,NP/A,765,294,2006) - angular O164800100026 distributions for elastic scattering(RTH) at 27 MeV. O164800100027 FACILITY (CYCLO,2BLGLVN) O164800100028 INC-SOURCE The exotic beam was produced using the proton beam O164800100029 from the cyclotron Cyclone-30 impinging on a LiF powderO164800100030 target via the reaction Li-7(p,2p)He-6. The atomic beamO164800100031 was ionized in an ECR ion source, purified by magnetic O164800100032 separation and post accelerated by a second cyclotron O164800100033 Cyclone-110 of the CRC facility. O164800100034 SAMPLE A self-supported foils of Pb-208 with a thickness O164800100035 of 0.950-mg/cm**2 were used as target. O164800100036 In order to increase the counting rate at the highest O164800100037 laboratory energy of 22 MeV a target foil of O164800100038 2.080-mg/cm**2 was used. O164800100039 The targets had the following isotopic composition- O164800100040 Pb-208 87(2)%, Pb-207 1.20(2)%, Pb-206 11.4(2)%. O164800100041 MONITOR (82-PB-208(A,EL)82-PB-208,,DA) this reaction was O164800100042 measured to normalize data and to cancel systematic O164800100043 errors in the He-6+Pb-208 elastic cross sections. O164800100044 DETECTOR (TELES,SISD,SISD) The reaction products were detected O164800100045 in a detection system consisting of a LEDA, a LAMP and O164800100046 DINEX. LEDA- silicon strip detectors. The DENIX O164800100047 detector array consists of four 90-degree circular O164800100048 silicon telescopes, of thickness 40 mum(front) and O164800100049 500 mum(back). LEDA, LAMP and DINEX detector arrays O164800100050 cover three different angular ranges- O164800100051 -LEDA 5-10-degree with an angular resolution of 0.5- O164800100052 degree, O164800100053 -LAMP 20-64-degree with an angular resolution of O164800100054 3-degree, O164800100055 -DENIX 135-170-degree with angular resolution of 5- O164800100056 degree. O164800100057 An average energy resolution for the LEDA array was O164800100058 150 keV and 250 keV for the DiNEX. O164800100059 METHOD (TOF) O164800100060 (EDE) O164800100061 CORRECTION The elastic scattering yield was corrected for the O164800100062 beam misalignment using a standard method.
