A014400100012 REL-REF (A,,W.A.Fowler+,J,RMP,20,236,1948) A014400100013 these data were included in 'data-section' by author. A014400100014 SAMPLE The targets comprised a series of identical discs A014400100015 machined (dry) from a block of Acheson graphite. A014400100016 They were mounted in quick-change probe, which A014400100017 permitted easy insertion into and removal from the A014400100018 target chamber of an electrostatic accelerator.

A014400200004 COMMENT /By author/.loss of N-13 by diffusion out of the A014400200005 graphite was considered negligible at the moderate A014400200006 temperatures developed in the targets, as no build- A014400200007 up of activity was detected by a shielded Geiger A014400200008 counter placed in the exhaust line of the target A014400200009 pumping system. A014400200010 ERR-ANALYS (DATA-ERR) Relative error. A014400200011 (ERR-SYS) Absolute error. This error includes A014400200012 * the error of the strength of 'standard' A014400200013 Na-22 source /5.5%/ and A014400200014 * systematic error due to radiation scattered into A014400200015 annihilation channel.
