M. Hino et al., Measurement of transverse coherent separation of spin precessing neutron using spin splitters, J PHYS CH S, 60(8-9), 1999, pp. 1603-1605
The authors have carried out measurement of a maximum length of transverse
coherent separation by means of spin precessing neutrons and spin splitters
. We have measured the spin precession when the transverse separation is up
to 4.0 pm using a spin interferometer in MINE in JAERI. We interpreted tha
t the loss of the visibility of the spin interference is caused from less o
verlap of coherent probability distribution of up arrow and down arrow spin
neutron waves. Furthermore we have installed a neutron spin interferometer
at ULS in JAERI in order to research the existence of an intrinsic maximum
coherent separation. The results shows the feasibility of the measurement
of the coherent separation with a well monochromatic beam (C) 1999 Elsevier
