New experimental data, compilation and evaluation for the Cu-nat(alpha, x)Ga-66, Cu-nat(alpha, x)Ga-67 and Cu-nat(alpha, x)Zn-65 monitor reactions

In the context of a systematic investigation of monitor reactions for charg ed particle beams, a detailed compilation and critical comparison of the ea rlier published data for the Cu-nat(alpha, x)Ga-66, Cu-nat(alpha, x)Ga-67 a nd Cu-nat(alpha, x)Zn-65 reactions have been performed. To solve the surpri singly large discrepancies found in the literature we also performed a new series of cross-section measurements up to 40 MeV for the above mentioned r eactions. We discuss the reasons for the discrepancies and provide reliable numerical Values for a recommended database. The new experimental values a nd selected literature data were compared with the predictions of different model calculations. The selected experimental data sets were fitted using different methods to obtain recommended values. (C) 2000 Elsevier Science B .V. All rights reserved.
