O130100100025 SAMPLE A 1023 mg/cm2 thick beryllium target placed at the O130100100026 entrance to the Projectile Fragment Separator (FRS). O130100100027 DETECTOR (SPEC,SCIN,IOCH) O130100100028 FACILITY (SYNCH,2GERGSI) O130100100029 The reaction products were separated by fragment O130100100030 separator (FRS). The FRS operated in the standard O130100100031 achromatic mode. The FRS, combining two stages of O130100100032 magnetic selection and an energy loss in a degrader, O130100100033 allows a full identification of reaction products with O130100100034 respect to their nuclear charge Z and mass A. O130100100035 METHOD (EXTB) A 1 A GeV 238U beam in spills lasting 6 seconds O130100100036 with a repetition period of 10-18 seconds. The primaryO130100100037 beam intensity was of the order of 1.0e+8 ions/spill. O130100100038 (BCINT) The 238U intensity was recorded by a O130100100039 secondary-electron transmission monitor.

O130100100046 CORRECTION Due to the fact that the half-lives of 218-Th and O130100100047 219-Pa, 109(13) and 53(10) nanoseconds, respectively, O130100100048 are shorter than their time-of-flight through the O130100100049 separator (170 ns in the eigen-frame of the fragment).O130100100050 Therefore, for these nuclei a correction for O130100100051 decay-losses was applied.

O130100200004 FLAG (1.) There are indications for the occurrence of a few O130100200005 events at the positions corresponding to 208-Th and O130100200006 211-Pa. However, the statistics and the resolution of O130100200007 the ion identification procedure at this setting were O130100200008 not sufficient to claim unambiguous observation of O130100200009 these isotopes. Thus, only upper limits for the O130100200010 corresponding production cross-section can be given.
