Résumé :

The Lagrange-mesh R-matrix method is generalized to inhomogeneous equations. This method is numerically stable and efficient. It can be directly used for transfer reactions with the formalism discussed by Ascuitto and Glendenning [Phys. Rev. 181, 1396 (1969)10.1103/PhysRev.181.1396] and for inclusive breakup reactions modeled by Ichimura, Austern, and Vincent [Phys. Rev. C 32, 431 (1985)10.1103/PhysRevC.32.431]. We first present a simple example to assess the method. Then the application to the Nb93(d,pX) nonelastic breakup is discussed.
