The Hussein-McVoy formula for inclusive breakup revisited: A Tribute to Mahir Hussein

In 1985, Hussein and McVoy [Nuc. Phys. A445 (1985) 124] elucidated a formula for the evaluation of the nonelastic breakup (stripping) contribution in inclusive breakup reactions. The formula, based on the spectator core model, acquires a particularly simple and appealing form in the eikonal limit, to the extent that it has become the standard procedure to analyze single-nucleon knockout reactions at intermediate energies. In this contribution, a critical assessment of this formula is presented and its connection with other, noneikonal expressions discussed. Some calculations comparing the different formulae are also presented for the one-nucleon removal of 14O+9Be reaction at several incident energies.

Automated summary

In 1985, Hussein and McVoy introduced a formula for evaluating the nonelastic breakup contribution in inclusive breakup reactions, which has become the standard procedure for analyzing single-nucleon knockout reactions at intermediate energies due to its simple and appealing form in the eikonal limit. This contribution critically assesses the formula and discusses its connection with other noneikonal expressions, presenting calculations comparing different formulae for the one-nucleon removal of the 14O+9Be reaction at various incident energies.
