  In recent years, several experiments using magnetic spectrometers provided
high precision results in the field of Hypernuclear Physics. In particular, the
accurate determination of the Lambda-binding energy, B(Lambda), contributed to
stimulate considerably the discussion about the Charge Symmetry Breaking effect
in Lambda-hypernuclei isomultiplets. We have reorganized the results from the
FINUDA experiment and we have obtained a series of B(Lambda) values for
Lambda-hypernuclei with A <= 16 by taking into account data only from magnetic
spectrometers implementing an absolute calibration of the energy scale (FINUDA
at DAFNE and electroproduction experiments at JLab and at MaMi). We have then
critically revisited the results obtained at KEK by the SKS Collaboration in
order to make possible a direct comparison between data from experiments with
and without such an absolute energy scale. A synopsis of recent spectrometric
measurements of B(Lambda) is presented, including also emulsion experiment
results. Several interesting conclusions are drawn, among which the equality
within the errors of B(Lambda) for the A = 7, 12, 16 isomultiplets, based only
on recent spectrometric data. This observation is in nice agreement with a
recent theoretical prediction. Ideas for possible new measurements which should
improve the present experimental knowledge are finally put forward.
