/* In the reference data given are not corrected for acceptance. In
this work, 11Be*(IAS) decays in two ways: 11Be*(IAS) -> 9Li+p+n
(direct decay) and 11Be*(IAS) -> 10Li+p ->9Li+p+n (Sequential
decay). The author assumed direct decay in the evaluation of
acceptance. To avoid ambiguity due to this assumption, authors gave
raw data (not corrected by acceptance) in the reference. */
