The lowest energy bound state has been analyzed for an electron trapped at the intersection of two identical narrow channels quantum wires, crossed at an arbitrary angle with the cross-section area in the form of a square. When the channels are perpendicular, such a classically unbound electron system is known to possess a quantum bound trapped state. A new improved trial wave function is proposed and used to tackle the problem. The S-type wire intersection preserves the bound state even at angles close to zero degree. These results supplement a theory of quantum bound states in classically unbound systems and may be useful to interpret electron transport peculiarities in realistic systems such as semiconductor nanowire films and carbon nanotube bundles.
