Summary
The rate and angular distribution of knock-on neutrons in polarized-muon capture by spinless nuclei is calculated in a simple statistical model, and compared with experimental data and other calculations.
Riassunto
In un semplice modello statistico si calcola il rapporto e la distribuzione angolare dei neutroni espulsi nella cattura di muoni polarizzati in nuclei senza spin e li si confronta con i dati sperimentali ed altri calcoli.
Реэуме
В простои статистическои модели вычисляутся интенсивностя и угловое распределение выбитых неитронов при эахвате поляриэованных муонов ядрами с нулевым спином. Проводится сравнение с зксперименталяными данными и с другими вычислениями.

There is good experimental knowledge of the separation energies for higher levels. For the deeper shells the determination is more uncertain, but their contribution to the neutron emission is very small. See, for example,G. J. Jacob andTh. A. J. Maris:Rev. Mod. Phys.,38, 121 (1966);H. Tyrén, S. Kullander, O. Sundberg, R. Ramachandran, P. Isacsson andT. Berggren:Nucl. Phys.,79, 321 (1966);A. N.
