“…In the first place previous RPA calculations [8,9] predict that there should be a compact monopole resonance located somewhere between 20 and 25 MeV excitation, while a more recent calculation m the framework of the selfconslstent continuum RPA predicts that the monopole strength in 40Ca should be fragmented [10]. The other reason is that nearly all experiments [1,6,[11][12][13][14][15][16][17] the E0 EWSR in the region betv een 16 and 20 MeV excitation energy [1,6]. We have used two independent methods to determine monopole strength, both of which have been used previously, but only separately or at least not mdependently as m the present experiment: singles measurements and coincidences with a-decay to the 0 + ground state of the residual nucleus 36At at very forward scattering angles.…”
