"Estimating scattering potentials in inverse problems with Volterra 
series and Neural Networks"


     címmel tartandó szemináriumára.


Kivonat:



Inverse problems often occur in nuclear physics, when an unknown 
potential has to be determined from observables such as cross sections 
or phase shifts. In this talk I propose two data-driven methods, using 
Volterra series and Neural Networks, where the scattering potentials can 
be estimated with good accuracy from experimentally available data in 
the Fourier domain and in position space as well. The Neural Network 
model is then used to describe the low energy 3S1 NN scattering at fixed 
angular momenta, giving a result within a few percent relative errors 
for the re-calculated phase shifts in a wide range of laboratory 
energies. The extension of the model for the fixed energy and varied 
angular momenta case will also be addressed.
