The telescope has a 2191900100026 mean Z (charge) resolving power Z/AZ of -40. 2191900100027 ANALYSIS To get the dependence of delta E on Z and E 2191900100028 the spectra were analyzed by putting a 2191900100029 window on the fragment energy (2MeV wide). 2191900100030 PART-DET (LF) 2191900100031 ERR-ANALYS (DATA-ERR) No details given 2191900100032 COMMENT From the author: As regards the issue thermal-cold it 2191900100033 is correctly said in the paper by Asghar that the IH1 2191900100034 beam of the ILL is cold. However, the beam IH1 has a 2191900100035 wavelength peak at 3.2 A corresponding to a neutron 2191900100036 energy of 8 meV, while thermal neutrons have 1.8 A 2191900100037 with the energy being 25 meV. The beam IH1 is hence 2191900100038 only "slightly cold". 2191900100039 STATUS (TABLE) Table 2a,b of Nucl.Phys.,A425(1984)120 2191900100040 HISTORY (19850124C)HH. 2191900100041 (19851002U)HH. 2191900100042 (19860304U) N.Ch 2191900100043 (20110304A) SD:Updated to new date formats,lower case. 2191900100044 Corrections in all Subents.
