This paper combines the results due to interactions of 40Ar at two energies 1.00 and 1.88A GeV in emulsion targets. We discuss and identify the projectile fragments with charge 2 {<=} Z {<=} 18. The identification of projectile fragments is based on two measuring methods {delta}-ray and gap density. The charges tend to appear in groups Z(2 -8), (9 - 13) and Z {>=} 14 with a positive long-range correlation. A polynomial function form describes well the {delta}-ray multiplicity distributions correlating the two used 40Ar beams with each other. A correlation between the average values of {delta}-ray and gap densities is depicted. We can correlate the values of {delta}-ray density per fragment and the corresponding gap densities with the fragment charge.
