And the counting time was equal 3032200100030 to the irradiation,unless the shortening of the former 3032200100031 was necessary to avoid the 'long-lived' nuclide decay. 3032200100032 After a pause of 5 to 10 half-lives of nuclide, a 2nd 3032200100033 measurement with the same counting time as the 1st one 3032200100034 was followed. 3032200100035 DETECTOR (NAICR) NaI(Tl) 3 * 3inch, with a 400-channel analyser 3032200100036 Victoreen ST 400 dm. 3032200100037 (SCIN) Scintillation counter, Hornyak NE 450, with a 3032200100038 photomultiplier EMI6097F for neutron monitoring. 3032200100039 PART-DET (DG,B+) Decay gammas or decay beta+. 3032200100040 CORRECTION The dead time of the multichannel analyser was correct-3032200100041 ed. 3032200100042 ANALYSIS When the same isomer arises from two different isotopes3032200100043 of the same elements as a result of the (n,n') and 3032200100044 (n,2n) reactions, the weighed mean cross-section was 3032200100045 calculated, taking isotopic abundances as weights. 3032200100046 DECAY-DATA Mainly taken from the Table of Isotopes,Lederer et al.,3032200100047 6th ed.,1967. 3032200100048 ERR-ANALYS (DATA-ERR) Total error is given. The large errors 3032200100049 for some of cross-sections may partially be due to 3032200100050 instrumental imperfections and to the fact that the 3032200100051 cross-section was not the main purpose of this 3032200100052 facility of automatic activation analysis. 3032200100053 COMMENT In a few cases the conversion coefficient is not 3032200100054 known, and is assumed to be 0 with the number of 3032200100055 quanta per disintegration to be 1. 3032200100056 STATUS (TABLE) From table 1 of J.Radioanal.Chem.,14(1973)201. 3032200100057 (APRVD) Approved by Janczyczyn with notes, 29/04/1976.
