(Li6,d) reaction onCa

Isoscalar dipole transition as a probe for asymmetric clustering

“…The α + 40 Ca cluster states in 44 Ti have also been studied by many authors [68][69][70]79,[89][90][91][92][93][94][95][96][97][98], but the situation is more complicated than the case of 20 Ne. The theoretical and experimental studies are summarized in a review paper [99], and our discussion is based on the assignment given therein.…”

Resonance spectroscopy of44Ti in the excitation energy range 9.05 to 10.28 MeV

“…A positive parity band with a dominant 4~ plus c~-cluster structure has been predicted [18] with E* =9.47 MeV(0+), 9.99 MeV(2 +) and 11.02 MeV(4+). The predicted 0 + level is stated [18] to be a strong candidate for the experimentally observed [19] level at 8.54 MeV. The present results indicate levels with large c~-widths at 9.12MeV(24.)…”

Possible higher order processes seen in four-nucleon transfer

“…As an example the reaction 4~ 6Li, d)~'~Ti( 3-)3.94 is considered. We have examined whether the strengths observed [9,12] were consistent with two-step reaction mechanism including inelastic excitation of the collective 3 i-octupole state of both the target and the final nucleus.…”

“…ZR-CCBA predictions and experiment. Experimental points for 32 MeV from [9], for 28 MeV from [12] reason of computational limitations the effect of additional inelastic channels, such as the next probably most important ones belonging to the 5-, 7-states in +~ and ++Ti, were taken into account by the imaginary potentials only. The theoretical curves corresponding to the different coupling schemes of Figure 1 are presented in Figure 2.…”
