Cross sections for (d–t) neutron interaction with germanium isotopes

Abstract

Abstract The cross sections for ( n , x ) reactions with Ge isotopes were measured at ( d – t ) neutron energies around 14 MeV with the activation technique using metal discs of natural composition. Calculations of detector efficiency, incident neutron spectrum and correction factors were performed with the Monte Carlo technique (MCNP4C code). Cross sections data are presented for 70 Ge( n , 2 n ) 69 Ge, 74 Ge( n , α ) 71 m Zn, 76 Ge( n , 2 n ) 75( m  +  g ) Ge, 70 Ge( n , p ) 70 Ga and 72 Ge( n , 2 n ) 71 g Ge reactions. The cross section results for 72 Ge( n , 2 n ) 71 g Ge reaction were reported for the first time. Some other cross sections were obtained with higher precision, including the 70 Ge( n , p ) 70 Ga reaction. Theoretical calculations of excitation functions were performed with the TALYS-1.0 code and compared with the experimental cross section values. Data were included in the EXFOR database.
