L028100100013 SAMPLE The target material was made of naturally occurring L028100100014 samples of calcium metal. Since Ca40 is present L028100100015 naturally to 96.97% and the remaining Ca isotopes are L028100100016 expected to scatter in a manner similar to Ca40, we L028100100017 do not make the small correction required for the L028100100018 presence of other calcium isotopes. L028100100019 METHOD Scattered electrons pass through the spectrometer and L028100100020 are detected in the ten-channel ladder. The relative L028100100021 efficiencies of the different channels were measured L028100100022 as usual by using a carbon target to provide a Rat L028100100023 inelastic continuum over the energy interval L028100100024 corresponding to the ten channels. As is usual with L028100100025 such measurements, four or five energy settings of L028100100026 the spectrometer are employed so that the peak L028100100027 appears in a different channel in each setting. The L028100100028 results are then combined by the computer program. In L028100100029 this way the effects of changing relative L028100100030 efficiencies can be averaged out. L028100100031 ERR-ANALYS (ERR-S) The errors given are only statistical in L028100100032 nature. L028100100033 CORRECTION Corrected for the channel efficiencies, radiative L028100100034 corrections, spectrometer dispersion, etc. L028100100035 HISTORY (20221004C) BP L028100100036 ENDBIB 34 0 L028100100037 COMMON 3 3 L028100100038 EN EN-ERR ANG-RSL L028100100039 MEV MEV ARAD L028100100040 250.0 1.5 0.033 L028100100041 ENDCOMMON 3 0 L028100100042 ENDSUBENT 41 0 L028100199999 SUBENT L0281002 20221004 20240513 L028100200001 BIB 2 2 L028100200002 REACTION (20-CA-40(E,EL)20-CA-40,,DA) L028100200003 STATUS (TABLE,,M.Croissiaux,J,PR,137,B865,1965) Table I L028100200004 ENDBIB 2 0 L028100200005 NOCOMMON 0 0 L028100200006 DATA 3 26 L028100200007 ANG DATA ERR-S L028100200008 ADEG MB/SR MB/SR L028100200009 32.0 7.48E-01 0.41E-01 L028100200010 35.0 2.18E-01 0.12E-01 L028100200011 40.0 5.16E-02 0.18E-02 L028100200012 43.0 2.30E-02 0.09E-02 L028100200013 45.0 1.16E-02 0.04E-02 L028100200014 47.0 5.09E-03 0.20E-03 L028100200015 50.0 1.62E-03 0.07E-03 L028100200016 52.0 7.85E-04 0.78E-04 L028100200017 53.0 8.22E-04 0.40E-04 L028100200018 54.0 5.46E-04 0.55E-04 L028100200019 55.0 5.46E-04 0.30E-04 L028100200020 56.0 5.42E-04 0.33E-04 L028100200021 57.0 4.37E-04 0.19E-04 L028100200022 58.0 5.46E-04 0.40E-04 L028100200023 60.0 4.97E-04 0.19E-04 L028100200024 65.0 4.28E-04 0.22E-04 L028100200025 70.0 3.07E-04 0.13E-04 L028100200026 75.0 1.55E-04 0.07E-04 L028100200027 78.0 7.76E-05 0.40E-05 L028100200028 85.0 2.26E-05 0.13E-05 L028100200029 90.0 7.46E-06 0.30E-06 L028100200030 95.0 1.66E-06 0.21E-06 L028100200031 100.0 1.70E-07 0.57E-07 L028100200032 105.0 3.58E-07 0.60E-07 L028100200033 115.0 4.44E-07 1.00E-07 L028100200034 125.0 2.93E-07 0.80E-07 L028100200035 ENDDATA 28 0 L028100200036 ENDSUBENT 35 0 L028100299999 SUBENT L0281003 20221004 20240513 L028100300001 BIB 2 2 L028100300002 REACTION (20-CA-40(E,INL)20-CA-40,PAR,DA) L028100300003 STATUS (TABLE,,M.Croissiaux,J,PR,137,B865,1965) Table II L028100300004 ENDBIB 2 0 L028100300005 COMMON 4 3 L028100300006 E-LVL E-LVL E-LVL E-LVL L028100300007 MEV MEV MEV MEV L028100300008 3.35 3.73 3.9 4.48 L028100300009 ENDCOMMON 3 0 L028100300010 DATA 4 22 L028100300011 ANG DATA ERR-S DATA-APRX L028100300012 ADEG MB/SR MB/SR MB/SR L028100300013 32.0 0.0 L028100300014 35.0 17.6E-04 17.0E-04 L028100300015 40.0 70.00E-04 20.00E-04 L028100300016 43.0 58.66E-04 8.40E-04 L028100300017 45.0 52.97E-04 5.30E-04 L028100300018 47.0 43.21E-04 2.70E-04 L028100300019 50.0 37.00E-04 1.60E-04 L028100300020 53.0 21.15E-04 0.80E-04 L028100300021 55.0 23.42E-04 0.80E-04 L028100300022 57.0 13.16E-04 0.36E-04 L028100300023 60.0 10.00E-04 0.35E-04 L028100300024 65.0 5.17E-04 0.36E-04 L028100300025 70.0 2.92E-04 0.30E-04 L028100300026 75.0 1.49E-04 0.15E-04 L028100300027 78.0 9.65E-05 1.00E-05 L028100300028 85.0 4.02E-05 0.50E-05 L028100300029 90.0 2.58E-05 0.02E-05 L028100300030 95.0 1.86E-05 0.40E-05 L028100300031 100.0 8.80E-06 4.00E-06 L028100300032 105.0 5.14E-06 0.35E-06 L028100300033 115.0 2.75E-06 0.27E-06 L028100300034 125.0 8.94E-07 2.00E-07 L028100300035 ENDDATA 24 0 L028100300036 ENDSUBENT 35 0 L028100399999 ENDENTRY 3 0 L028199999999
