La Jolla Natural Radiocarbon Meaurements V

Abstract
In all measurements reported in La Jolla I through IV and for the first of those herein reported (LJ-994 to LJ-1025 and LJ-GAP-1 to LJGAP-15), we followed the procedure designed by Suess (1954) in producing acetylene (C2H2) for radiocarbon counting. For the subsequent samples, however, the following reaction for C2H2synthesis was used:
