On the form function and properties of modified nineteen-tubular powder II

A second form of the modified nineteen-tubular powder (with one hole in the centre and the remaining 18 holes in 3 rings, each having 6 holes) has been studied. The form function for such powder (called the modified nineteen-tubular powder II) has been derived. Tables for various constants occurring in the treatment have been prepared for some sets of values of m and p.
