The angular distribution for the quasi‐elastic scattering of the halo nucleus 11Be from 209Bi has been measured at 40 MeV beam energy. The measurement performed with a beam intensity of ∼ 104 Hz could be done due to a ∼ 4π array based on high granularity Si detectors. The 11Be (Sn = 0.504 MeV) angular distribution was found to be nearly equal to that of 9Be (S2α+n = 1.574 MeV), i.e. with quite similar reaction cross section. This means that the influence of low binding energy and/or halo structure onto reaction dynamics has to be better understood.

Abstract
The angular distribution for the quasi‐elastic scattering of the halo nucleus 11Be from 209Bi has been measured at 40 MeV beam energy. The measurement performed with a beam intensity of ∼ 104 Hz could be done due to a ∼ 4π array based on high granularity Si detectors. The 11Be (Sn = 0.504 MeV) angular distribution was found to be nearly equal to that of 9Be (S2α+n = 1.574 MeV), i.e. with quite similar reaction cross section. This means that the influence of low binding energy and/or halo structure onto reaction dynamics has to be better understood.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
