Experimental elastic and quasi-elastic angular distributions provide transfer probabilities

Following a similar approach suggested recently to derive breakup probabilities [Phys. Rev. C 92, 054620 (2015)], we present a simple method to derive transfer probabilities by measuring only elastic or quasi-elastic scattering for the system under investigation with the positive transfer $Q$ values and a similar system with closed transfer channels. Our estimations and transfer data for the two-neutron stripping in the ${}^{18}\mathrm{O}+{}^{206}\mathrm{Pb}$ reaction are in a reasonable agreement.

The two-neutron transfer probabilities of Eq. (9) [Eq. (10)] (circles) are compared with the available data for ${}^{18}\mathrm{O}$ + ${}^{206}\mathrm{Pb}$ at energy $E_{\mathrm{lab}}=79$ MeV (squares) [14].
