AUTHOR (A.ARCHENTI,C.WASILEVSKY,M.DE LA VEGA VEDOYA, S.J.NASSIFF) REFERENCE (J,RCA,38,65,85) REL-REF (A,R0052001,MARTIN+,J,NP,89,481,68) INSTITUTE (3ARGCNE) FACILITY (SYNCY,3ARGCNE) METHOD (EXTB,STTA,EDEG) (ACTIV) Irradiation Time is not Given. Cooling Time is Not Given Too. The Information is Needed Because Cross- Section of Short-Lived Isotopes were Measured. Yb-167 - Half-Life is 17.7 Minutes. Yb-165 - Half-Life is 9.9 Minutes. If the Radiations of Daughter Nuclides were Measured, Then Cumulative Cross Sections of the Daughters were Measured, But not Independent Cross Section For Yb-167 And Yb-165 Production. (GSPEC) SAMPLE Target-Natural Erbium. Stacks of Natural Erbium Foils,0.012G/Cm**2 Thickness, Were Irradiated in the External Beam of the 60 Inch Synchocyclotron. DETECTOR (GE-IN) ANALYSIS (AREA) ADD-RES (TTY-C).The Thick Target Yields For Yb-169-G and Yb-166 Production were Recalculated Through Numerical Integration, Applying Experimental Cross Section Values Obtained in the Present Work. COMMENT /by Compiler/.The Authors Gave Noany Information For Averaging Their Data at Different Monitor.

CRITIQUE Decay Data For Investigated Products are not Given by Authors. Therefore Data Evaluation is Hindered. Compiler Included Half-Lives from ENSDF. HISTORY (861227C) (980612A) Method and Reaction Lines are Corrected. Lower Case. Comments and Critique are Added. (980619U) Last checking has been done.
