Superbarrier

The energy and angular distribution of the fragments observed in nuclear emulsion (Z=3 to appromixately 7) show the existence of many superbarrier fragments directed along the incident beam direction.

It is shown that at electron scattering by a crystal atoms chain a phenomenon of rainbow scattering of superbarrier particles occurs. It is shown that at small angles psi the mean square scattering angle on crystal atom chains considerably exceeds the mean square scattering angle in amorphous medium and that maximum of these values ratio is attained under psi scale of the critical angle of channeling.

A maximum transmission of a general kind is solved and the solution is used to give a general interpretation of the necessary condition. The sub- and superbarrier cases are treated in a unified way.

The combined effect of using couple-based LICOs to regulate access to social assistance and tax benefits produces superbarriers to the labour force participation of women who receive social assistance.

Superbarriers could change the packaging rules.
