Coupled channel approach to subbarrier fusion cross section

  • Published:
Zeitschrift für Physik A Atomic Nuclei

Abstract

We present a reduced coupled channel method to treat a large number of coupled equations. This method is shown to be a good approximation to the exact coupled channel method for the fusion calculation even in the system involving strong coupling to high spin states. This method is applied to the analysis of subbarrier fusion cross sections for148,150,154Sm+16O,232Th+16O and236U +12C. We show that the channel coupling to low-lying collective states can explain the magnitude of the fusion cross sections, whereas it underestimates the measured mean square values of spin distribution for232Th+16O and236U+12C. This discrepancy is discussed from the viewpoint of the WKB model.
