Abstract	The purpose of this work was to study the claim of the R416 group to be able to observe the production of 'beauty' at the Split-Field Magnet (SFM) facility of the CERN Intersecting Storage rings (ISR). The two basic points of these authors were: (i) by using an improved 'new' version of the reconstruction programs, a factor approximately 9 in efficiency can be achieved with respect to the 'old' SFM reconstruction programs; (ii) with two Cerenkov counters, each 1 m long, and each with a large area of coverage as in the SFM structure, a rejection power of 1.5*10/sup -4/ against charged hadrons can be achieved.
