We scanned Brho2 values so that the yield for 36Ca is maximized (LISE run0282-0284, F31 = +/-6 mm). 

Attachment 1:
Yields of 32S, 30P, 29Si (strong contaminants) and 36Ca as a function of the Brho2 value.
We can see that different contaminants dominate if the Brho2 setting is changed. The shaded region corresponds to the momentum spread
determined by the slit F43 (0.25%, shown only for DeltaBrho2 = 0%). The 36Ca yields are too small to see.

Attachment 2:
36Ca yields that cannot be seen in the previous figure.

Attachment 3:
Fitting of 36Ca yields assuming that the distribution is a Gaussian.
