Absolute cross section of the reactionCa48(O

Abstract

It is shown that the long standing difficulty of very small theoretical cross sections for heavy-ion-induced twonucleon transfer reactions appears to have been solved, at least for the case of the 'Ca("0, ' 0)' Ca reaction.NUCLEAR REACTIONS Ca(' 0, ' 0) Ca, E=50 MeV, 0 ground state and 2 excited state. DWBA and coupled-reaction-channel analysis, density-dependent correlations.

A note on some problems in transfer calculations

“…Therefore, the usual neglect of 0k, 02 and 0 6 channels in CRC seems well founded in that case. In a number of recent publications, two-particle transfer cross sections has been calculated with breave attemps to surmount the related numerical diffifuclties [7,8].…”

Two-proton transfer reaction48Ca(18O,16C)50Ti at 102 MeV

“…These factors still indicated either a considerable underestimate of configuration mixing or the presence of other competing reaction mechanisms [5,6,7]. For the 48Ca(180, 160)5~ reaction it was shown [7] that the normalization factor 5 obtained [-4] in the calculation assuming a direct simultaneous two-neutron transfer could be reduced to unity if a successive twoneutron transfer process was included.…”
