    keyword=Target - EPR

    17:20 EPR measurement

    Conditions: position: pick-up, laser #6 on, trans. grad. coil: +5.00 A,
    long. grad. coil: -2.00 A, beam: off

    P > 42 %

    Comment: First spin flip happened very late (effect of integration time?) and
    frequency shift did NOT reach minimum.

    I still analysed the run, but DON'T trust these numbers:

    0th order fit:

    freq shift:
    down: -51.0 kHz +/- 2.8 kHz
    up: 45.2 kHz +/- 2.6 kHz

    pol's
    down: 42.4 % +/- 3.2 %
    up: 40.8 % +/- 3.2 %

    Decided not to try another EPR-AFP sweep.

    Just to make sure that this is not real, performed a 2nd NMR measurment
    and the polarisation is still high (see separate entry).
