In the paper a new algorithm to find peaks in two, three and multidimension
al spectra, measured in large multidetector gamma-ray arrays, is derived. G
iven the dimension in. the algorithm is selective to in-fold coincidence pe
aks. It is insensitive to intersections of lower-fold coincidences, hereina
fter called ridges. (C) 2000 Elsevier Science B.V. All rights reserved.
