On the applicability of classical description to the statistical angular distributions in heavy ion reactions

Abstract

The analysis of classical description of the statistical angular distributions is given and the criterion of its applicability is obtained by the comparison with the exact quantal calculations. It is shown that the approach considered can be applied to a wide range of experiments dealing with the compound heavy ion reactions.

“…(8) and (9)) on neuton scattering angle for different heavy-ion reactions. The system 82Kr has been investigated in [3], the other systems are taken from [7]. For comparison, the (angle-independent) results calculated according to the simple formula (13) are indicated by horizontal arrows…”

“…a classical rule for vector summation is used instead of the quantal one; and: ii) the spherical function formalism is replaced by the classical relation between orbital angular momentum and the direction of motion of the emitted particle. The applicability of the classical description to the statistical angular distributions in heavy-ion reactions has been justified in [7].…”
