Electromagnetic dissociation of 200 GeV/nucleon 16O and 32s ions in nuclear emulsions

Electromagnetic dissociation of ²³⁸U in heavy-ion collisions at 120 MeV/A

“…Price et al [13], Brechtmann et al [30,31], and Baroni et al (33]. All of these experiments used nuclear track detectors -CR-39 plastic in the case of Price and Brechtmann, nuclear emulsion in the case of Baroni.…”

Clustering in light nuclei in fragmentation above 1 A GeV

“…Experimental data on the charged topology for the final states of a number of light nuclei have been described in [2,3,4,5,6]. More specific studies were performed for the leading channels like 12 C → 3α [7], 16 O → 4α [8,9], 6 Li → dα [10,11], 7 Li → tα [12], 10 B → dαα [13], and 7 Be → 3 Heα [14].…”

Clustering in light nuclei in fragmentation above 1 A GeV

“…2 shows the b ik distribution (1) for the fragmentation channel 22 Ne→ nα for n equal to 3 (240 events), 4 (79 events), and 5 (10 events) which is rather narrow. The distribution "tails"appear to be due to the 4 He diffractive scattering or 3 He formation proceeding at higher momentum transfers. The events, satisfying the non-relativistic criterion b ik <10 −2 for each α particle pair were selected for n equal to 3 (141 events), 4 (47 events), and 5 (6 events).…”

“…Fig. 1 shows the microphotograph of a special example of a projectile fragment jet -the "white"star as introduced in [3]. It corresponds to the case of a relativistic nucleus dissociation accompanied by neither a target fragment nor meson production.…”
