“…Cross sections for populating excited states in 150,152 Sm via the (p,t) reaction have previously been measured in references [9][10][11][12]. In Table III the relative cross sections obtained in the present work for the 152 Sm(p,t) reaction are compared to those obtained by Debenham et al [11] and McLatchie et al [10].…”

“…In Table III the relative cross sections obtained in the present work for the 152 Sm(p,t) reaction are compared to those obtained by Debenham et al [11] and McLatchie et al [10]. Since the cross sections obtained in the present work are angle averaged between 34 to 58 degrees whereas the values quoted by Debenham are the maximum differential cross sections at the listed angle, this table is provided as a general comparison only.…”

“…Two-neutron transfer reactions provide an excellent tool with which to study both the removal of pairs of correlated neutrons from valence orbitals, typically populating states at relatively low excitation energies, as well as the removal of neutrons from deep below the Fermi surface. Following the work of Maxwell [7], further Sm(p,t) experiments were performed with improved energy resolution for the outgoing tritons, see for example [9][10][11][12], at various incident proton beam energies. In the 1981 study by Struble et al [13] a large, broad enhancement of two-neutron transfer strength at an excitation energy of approximately 6 MeV was observed in the 148,150,152,154 Sm(p,t) reactions.…”

OnE0 transitions in the decay of152Eu m (9.3 h)

“…The groundstate of 152Sm and the 0 + fl-vibrational state at 685 keV are assumed to have approximately the same deformation. On the other hand, the 0 + state at 1083 keV is regarded as being nearly spherical (as concluded from (p, t) reactions on 154Sm [22,23] and (t, p) reactions on 15~ [19,20]). The situation in 152Gd appears to be reversed, i.e.…”

(p, t) Reaction studies on some even isotopes of samarium

“…Up to an excitation any other reaction. Therefore this level seems to be quite similar to the 1.26 MeV level in 150Sm ' which is also only excited in the 15 ZSm (p, t) ~ 5 o Sm reaction [1,5,13] and is explained as a deformed 0 + state coexisting in the "spherical" nucleus ~5~ Recently a paper has been published by Debenham and Hintz [14] on investigations of (p, t) reactions in Sm-148, Sm-150, Sm-152 and Sm-154 at Ep=19 MeV. The results of the measurements on Sm-148 and Sin-150 target nuclides are in general agreement with the analysis given here.…”
