Spectra for 208Pb(alpha, alpha') taken with the Q3D magnetic spectrograph at MLL Garching (Germany) in 1992

Spectra for 208Pb 208Pb(alpha, alpha')
taken with E= 40.4 MeV with the Q3D magnetic spectrograph.

The detector had five layers read out separately,
an1 and an2 for anode-1 anode-2,
cat1 and cat2 for cathode-1 cathode-2,
foc for focal plane.

The distance between the wires was about 10 cm - in between the focal plane.

Strong peaks from contaminations of 12C and 16O were erased by
inserting a metal foil before the detector.

In 2015 an essay was done to analyze some spectra by GASPAN.
They are roughly calibrated by Nuclear Data Sheets 2007

Files needed for evaluation with GASPAN in GSPwork_2015.tgz
