COMMENT    The photoneutron angular  distributions  from  carbon  M045700100017 
            and   beryllium   have   been   measured   by  using  M045700100018 
            bremsstrahlung of maximum energies of 23 and 18 MeV,  M045700100019 
            respectively.  The  angular  distributions  obtained  M045700100020 
            are:  1 + (1.35 (0.88)) * (sin(theta))**2 for carbon  M045700100021 
            and (1.26 (0.11)) + (sin(theta))**2 for beryllium.    M045700100022
