O043300100009 SAMPLE The targets consisted of 0.5-in. squares of Cu-65 O043300100010 (enriched to 99.6%) vacuum deposited to a thickness O043300100011 of 2-3 ug/cm**2 onto 25-30 ug/cm2 formvar films. O043300100012 An additional angular distribution was obtained at O043300100013 2.8 GeV from targets with 6 ug/cm2 Cu-65 on 50 ug/cm2 O043300100014 formvar in order to estimate the effect of scattering O043300100015 of the Cu-64 recoils in the target and backing. O043300100016 In some irradiations an extra 0.00025-in. mylar foil O043300100017 was included under the catcher foil in order to O043300100018 determine the activation blank of Cu-64 from mylar O043300100019 impurities in the mylar.

O043300100034 (ERR-5) An additional systematic uncertainty is O043300100035 contributed to each of the angular distributions by O043300100036 the uncertainty in the total cross sections. O043300100037 CORRECTION A correction for 10 degree resolution of O043300100038 the collector foils was applied to all of the data O043300100039 obtained with the 2-3 ug/cm2 targets. This correction O043300100040 was computed at each angle from a quadratic function O043300100041 fit to the differential cross sections at that angle O043300100042 and the two immediately adjacent angles. O043300100043 The largest correction is seen to be about 2%. O043300100044 METHOD (ACTIV,CHSEP,REC) O043300100045 STATUS (TABLE) Tbl.
