Abstract
For carrying out experiments in the field of the so-called precise neutron optics (PNO), we have implemented special multi-purpose apparatus called th e "PNO-apparatus" at JRR-3M. Making use of an Si triple-laue (LLL) neutron interferometer with the PNO-apparatus, we successfully determined the coher ent neutron scattering lengths of gallium isotopes, Ga-69 and Ga-71. The re sults are 8.053 +/- 0.013 fm for Ga-69 and 6.170 +/- 0.011 fm for Ga-71, re spectively. (C) 1999 Elsevier Science B.V. All rights reserved.
