description:
	New data from Angle-resolved photoelectron spectroscopy (ARPES) suggest possible superlattice formation in superconducting cuprates at (pi/2, pi/2, 0).  This is the place in Q space never studied before, and it is possible that a hidden diffuse peak exists there.  Observation of this peak will completely change our view on the metal-insulator transition in doped Mott insulator.  We will use thin foil of BiSCCO single crystal, to be mounted in a displex, and use the 4-circle geometry with Kappa goniometer.  It will be useful if we can use a two-dimensional detector, but this is not absolutely necessary.
