Description
A review and analysis of experimental 4π-methods for total reaction cross section σ$_{\rm{R}}$ measurements are presented. The methods for σ$_{\rm{R}}$ measurements are based on the 4π-technique of registering prompt γ-quanta and neutrons in a solid angle close to the full angle Ω = 4π.
The description the method applied to measuring γ-detection efficiency ε(M$_{{\gamma}}$) for various values of γ-multiplicity M$_{{\gamma}}$ are presented. The experimental facility and 4π scintillation spectrometer for M${_{{\gamma}}}$ measurement are described.
The comparison and analysis of the two experimental 4π-methods developed at FLNR JINR, Dubna for σ$_{\rm{R}}$ measurements in the reactions with neutron-rich weakly bound nuclei are presented. The first method is based on the mean value of the detection efficiency <ε> which does not depend on γ-multiplicity M${_{{\gamma}}}$ [1]. In the second method, we use the experimentally obtained response function ${w_M}\left( k \right)$ (the distribution of the numbers of triggered detectors k in registration of γ-cascade with a fixed value of M${_{{\gamma}}}$) [2].
