The 3076100100022 authors found that there exists a weak structure in 3076100100023 the region 10-14 MeV of the LRA spectrum in the case 3076100100024 of angle 67deg laboratory system(the emission angle of33076100100025 the LRA with respect to the direction of the light 3076100100026 fragment). 3076100100027 ERR-ANALYS (E-ERR-DIG) Digitizing error of alpha energy 3076100100028 (ERR-DIG) Digitizing error of data 3076100100029 HISTORY (19871111C) WD. 3076100100030 (19890526U) VOF .- Status corrected - 3076100100031 (20090725A) SD:Updated to new date formats,lower case. 3076100100032 Cosmetic changes, additions.
