Calculation of angular and energy distributions for nuclear recoil reactions $sup 19$F($gamma$,n)$sup 18$F according to a quasi-deuteron model

The angular and energy distributions of the recoil nucleus /sup 18/F formed in the reaction /sup 19/F( gamma ,n)/sup 18/F under the influence of bremsstrahlung with a maximum energy of 260 MeV was calculated on the basis of a quasi-deuteron model for the absorption of high energy quanta by nuclei. Possible sources of discrepancy between experimental data and the results of the calculations were explored. (tr-auth)
