DETECTOR (SPEC) The 72-in. spectrometer and ten-channel L028100100012
counter were used in all the work. 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
