Popis:	Quantum and classical quasiresonant vibration-rotation energy transfer is investigated for ultracold He-H{sub 2} collisions. Classical trajectory computations show that extremely strong correlations between {Delta}j and {Delta}v persist at low energies, though the changes themselves are less than one quantum. Quantum computations show that quasiresonant transitions occur in the limit of zero collision energy but that threshold effects become important and that some quasiresonant channels close. The qualitative similarity between classical and quantum results suggests that they share a common mechanism. {copyright} {ital 1999} {ital The American Physical Society}
