Description

Excitation functions have been determined in the 10 to 20 MeV energy region for the reactions Ti 46(n,2n)Ti 45, Zn 66(n,2n)Zn 65, In 115(n,2n)In 114m (49.2 d) and Au 197(n,2n)Au 196 by means of the activation technique. There is considerable scatter among existing data for these reactions in the 13 to 15 MeV energy region. Evidence is discussed that these discrepancies are due to deviating assumptions for the decay schemes and insufficient energy resoltution of activity detectors in the past. For the reactions In 115(n,2n)In 114m and Au 197(n,2n)Au 196 the present results are confirming the lowest cross-sections from the existing data. (orig.)

Abstract (German)

Mittels der Aktivierungsmethode wurden Anregungsfunktionen fuer die Reaktionen Ti 46(n,2n)Ti 45, Zn 66(n,2n)Zn 65, In 115(n,2n)In 114 m (49,2 d) und Au 197(n,2n)Au 196 im Energiebereich von 10 bis 20 MeV bestimmt. Die bestehenden Daten zeigen eine erhebliche Streuung im Energiebereich von 13 bis 15 MeV. Diskutiert werden Anzeichen dafuer, dass diese Diskrepanzen auf abweichenden Annahmen ueber die Zerfallsschemata und unzureichender Energieaufloesung von Aktivitaetsdetektoren in der Vergangenheit beruhen. Fuer die Reaktionen In 115(n,2n)In 114 m und Au 197(n,2n)Au 196 bestaetigen die vorliegenden Ergebnisse die niedrigsten Werte der bestehenden Wirkungsquerschnitte. (orig.)
