In 1st series, total 2038100100031 discrimination level(aluminium absorption and 2038100100032 electronic bias) for ternary alpha was fixed at about 2038100100033 10 MeV, (preliminary results were reported in 2038100100034 EANDC(E)-123). In 2nd series this bias level was 2038100100035 increased to about 15 MeV. 2038100100036 HISTORY (19721211C) 2038100100037 (20190117A) SD:Updated to new date formats,lower case. 2038100100038 REACTION code in Subent 002 corrected according to 2038100100039 MEMO CP-D/969.
